Each screen's button kept its own open state and its own draft, so the
question half written on the Library was gone on Home. ComposerCubit,
provided beside ConversationDockCubit, now holds whether the field is
open and the draft (text, files attached, parts chosen) for every
button. Switching tabs keeps it as it is (AppShell says so before
goBranch); going to another screen within a tab, or over the tabs, keeps
it open only while something is written or attached. Only the button of
the screen at the router's location unfolds, so no tab kept alive
behind holds a second field.
Whats-New: The question you are writing stays open as you switch tabs.
Whats-New-De: Die Frage, die du schreibst, bleibt offen, wenn du den Tab wechselst.
