This Sphinx extension fixes:
- with a `layout` patch:
    - an issue where drop down menus would still take up space after being minimized, and the patch fixes it through some css.
    - an issue where in drop down code cells the shown summary remained lightgray instead of turning darkgrey. Fix through css.
    - an issue where the size of code in a header is not the correct font size. Fix through css.
    - an issue where the sidebar shows a scrollbar even if that's not needed
    - an issue where the margin causes a scroll bar for a window between 992 and 1200px.
    - an issue where the caption text of a figure is aligned on the left for multi-line caption text.
    - an issue where code inside code-cells are aligned according to the parent element, instead of left-aligned.
- with a `button` patch:
    - an issue where two buttons for interactive matplotlib widget do not appear.
- with a `mathjax` patch:
    - an issue where in the Firefox browser the CHTML renderer of MathJax does not render thin lines consistently. Fixed by selecting the SVG renderer *only* for the Firefox browser. 
    - an issue where rendered MathJax using the CHTML renderer is sometimes clipped at the top and/or the right. Fixed by adding some css to improve the appearance of MathJax elements.
    - that makes the default loading method of MathJax to be lazy loading, which improves page load times. Can be disabled if needed by either
      - disabling the `mathjax` patch (this also disables the Firefox fix); or
      - adding `ui/nonlazy` to `config.mathjax3_config['loader']['load']` in your config file as shown below. _This value is not defined by MathJax, but introduced by JupyterBook-Patches to allow disabling lazy loading._
        ```yaml
        sphinx:
          config:
            mathjax3_config:
              loader:
                load:
                  - "ui/nonlazy"
        ```
- with a `download` patch:
    - an issue where the standard download button for downloading `.ipynb` and `.md` files opens a new tab in some browsers instead of downloading the file. Fixed by adding the `download` attribute to the download links.
- with a `hash` patch:
    - an issue where if the URL contains a specific element id, the page scrolls to the element on the initial/partial page load and does not scroll to that element after complete page load. Fixed by adding a small javascript that scrolls to the element after complete page load.
- with a `preserve_dropdown_state` patch:
    - an issue where reloading a page causes all dropdown/collapsible admonitions to reset to their default state. Fixed by saving and restoring the open/closed state of all dropdowns using sessionStorage. Supports multiple dropdown types including:
        - `details.dropdown` - Standard HTML details dropdowns
        - `details.sd-dropdown` - Sphinx Design dropdowns
        - `details.toggle-details` - Toggle details elements
        - `div.dropdown` - Div-based admonition dropdowns with toggle buttons
- with a `margin` patch:
    - that allows the definition of margin/aside elements inside admonitions, instead of only outside. In other words:
    - a `margin` directive can now be nested within one other admonition.
    - a non-figure directive with the class `margin` can now be nested within one other admonition.
    - a figure directive with the figclass `margin` or `margin-caption` can now be nested within one other admonition.
    - Note that this not apply to `code-cell` directives, as those are not supported inside other directives.
- with a `mystnb` patch:
  - an issue where colon fences (such as `:::`) for top-level `code-cell`s were not allowed.
    - Colon fences (such as `:::`) for top-level `code-cell`s are now allowed, next to backtick fences (such as ```` ``` ````), inside markdown files.
  - an issue where the `include` directive did not correctly handle included content from markdown files with top-level `code-cell`s and/or YAML front-matter from markdown files.
    - The `include` directive now correctly handles included content from markdown files with top-level `code-cell`s and/or YAML front-matter from markdown files.
  - an issue where markdown files that contain and/or include top-level `code-cell`s were not ensured to be a text-based notebook file.
    - Markdown files that contain and/or include top-level `code-cell`s are ensured to be a text-based notebook file.
