Dont reflow when toggling evme-loading-from-input. Compared the visuals of before and after in the dock and they are exactly the same.

Stop reflowing on evme-keyboard-visible

Remove footer reflow on window resize

Remove reflows (unless required) in everything.me Scroll plugin

Some small reflows in helper.css code

Dont let the everything.me container steal pointer events from the homescreen if it's not active
