Release 4.234.0

The bottom bar hides all the way, and the composer stops repeating itself (the owner's phone screenshots, 11-13).

• The bottom bar (appbar.js). It stepped aside for a keyboard or an open panel with translateY(110%) while its lift above the visible viewport still applied, so above a keyboard, or with Android's toolbar gap, it stopped half on the screen. A hidden bar now drops the lift, sits fully below the screen, and is invisible and not clickable until it comes back.
• The + sheet. It no longer repeats a tool the row already shows; the emoji button and an "Emoji" tile side by side were the same thing twice. The sheet holds what a narrow row hides, and the extras (Timer, GitHub).
• The GitHub picker:
  • each row's mark is its owner's initial on a colour of the name; GitHub's own pictures were blocked by most sites' image policy, so every row showed a broken picture, and each one asked GitHub;
  • the same words are answered from the page's cache for ten minutes;
  • a new search cancels the one still running;
  • it waits a third of a second after the last key;
  • the list scrolls inside its panel and no longer runs over the box.
• Tests composer-v2-chrome (nothing repeated, the initial, the cache) and navbar-appbar (hidden is all the way).
