Two follow-ups to ending text editing on a click in another panel.
A press anywhere in a panel group focused the group's shown panel, even
a press on another of its tabs. Opening Properties or Character behind
Effects & Presets (as in Undocked Panels) therefore ended the edit on
the press, before the tab's click focused the panel chosen, and later
formatting went to the whole layer instead of the selected characters
(an empty Type-tool layer was even removed). A press on another tab now
waits for that tab's click.
The click away is resolved after the frame's panels, so keys that came
after it in the same frame's input were still typed into the text. The
text keyboard handler now takes the frame's keys in order up to a press
outside the viewer: keys before the click are typed, keys after it are
neither typed nor run as shortcuts, and from the next frame they are
the app's.
Tests: opening_a_formatting_tab_keeps_the_text_selection (a real click
on the Properties tab keeps the edit and its selection; Faux Bold then
styles only "Hello") and keys_after_a_click_away_in_the_same_frame_skip_
the_text ("A", a click on a Timeline row, then "x", Space and Delete in
one frame: only "A" is typed, nothing is played or deleted; Space in the
next frame plays). Both fail on the previous commit.
