Code before:
    return {
      covers,
      inputs,
      clickables,
    };
  }

  // If the item contains multiple clickable elements and/or inputs, then the item
  // should not have a clickable input cover over the entire item to prevent
  // interfering with their individual click events
  private setMultipleInputs() {
    const { covers, inputs, clickables } = this.totalNestedInputs();

    // Check for multiple inputs to change the position of the input cover to relative
    // for all of the covered inputs above
    this.multipleInputs =
      covers.length + inputs.length > 1 ||
      covers.length + clickables.length > 1 ||
      (covers.length > 0 && this.isClickable());
  }

  private setIsInteractive() {
    // If item contains any interactive children, set isInteractive to `true`
    const { covers, inputs, clickables } = this.totalNestedInputs();

    this.isInteractive = !!(covers.length + inputs.length + clickables.length);
  }

  // If the item contains an input including a checkbox, datetime, select, or radio
  // then the item will have a clickable input cover that covers the item
  // that should get the hover, focused and activated states UNLESS it has multiple
  // inputs, then those need to individually get each click
  private hasCover(): boolean {
    const inputs = this.el.querySelectorAll('ion-checkbox, ion-datetime, ion-select, ion-radio');
    return inputs.length === 1 && !this.multipleInputs;
  }

  // If the item has an href or button property it will render a native
  // anchor or button that is clickable
  private isClickable(): boolean {
    return this.href !== undefined || this.button;
  }

  private canActivate(): boolean {
    return this.isClickable() || this.hasCover();
  }

  private isFocusable(): boolean {
    const focusableChild = this.el.querySelector('.ion-focusable');
    return this.canActivate() || focusableChild !== null;
  }

Review comment (suggestion):
```suggestion
    this.isInteractive = covers.length || inputs.length || clickables.length;
```
This change request is very minor, but it's more obvious what you're doing at a glance and it allows short circuiting from the engine as soon as any of the checks pass. I don't know if the compiler is smart enough to see what you're doing here and break it out the same way when you're adding lengths like that, but even if it is I still think the readability would be improved. You can even omit the explicit boolean casting (`!!`) since that happens from the `||` operator.

Code after:

  private setIsInteractive() {
    // If item contains any interactive children, set isInteractive to `true`
    const { covers, inputs, clickables } = this.totalNestedInputs();

    this.isInteractive = covers.length > 0 || inputs.length > 0 || clickables.length > 0;
  }

  // slot change listener updates state to reflect how/if item should be interactive
  private updateInteractivityOnSlotChange = () => {
    this.setIsInteractive();
    this.setMultipleInputs();
  };

  // If the item contains an input including a checkbox, datetime, select, or radio
  // then the item will have a clickable input cover that covers the item
  // that should get the hover, focused and activated states UNLESS it has multiple
  // inputs, then those need to individually get each click
  private hasCover(): boolean {
    const inputs = this.el.querySelectorAll('ion-checkbox, ion-datetime, ion-select, ion-radio');
    return inputs.length === 1 && !this.multipleInputs;
  }

  // If the item has an href or button property it will render a native
  // anchor or button that is clickable
  private isClickable(): boolean {
    return this.href !== undefined || this.button;
  }

  private canActivate(): boolean {
    return this.isClickable() || this.hasCover();
  }

  private isFocusable(): boolean {
    const focusableChild = this.el.querySelector('.ion-focusable');
    return this.canActivate() || focusableChild !== null;
  }

  private hasStartEl() {
    const startEl = this.el.querySelector('[slot="start"]');
    if (startEl !== null) {
      this.el.classList.add('item-has-start-slot');
    }
  }

  private getFirstInteractive() {
    const controls = this.el.querySelectorAll<HTMLElement>(
      'ion-toggle:not([disabled]), ion-checkbox:not([disabled]), ion-radio:not([disabled]), ion-select:not([disabled]), ion-input:not([disabled]), ion-textarea:not([disabled])'
    );
    return controls[0];
  }
