After typing into a text layer, clicking another panel (a solid in the
Timeline, say) left the edit open, and the viewer took the keyboard back
as soon as nothing had the focus: typed characters went into the text
and Space added a space instead of playing.
A click in any panel other than the viewers and the panels that format
the selected characters (Character, Paragraph, Properties) now ends the
edit with text.endEdit, so the text is kept and an empty layer the Type
tool started is removed, and the viewer's text focus is surrendered. The
editor takes the keyboard back only after a click in the viewer or one
of those panels, no longer merely because nothing has the focus. A click
elsewhere in the viewer still commits, and with the Type tool still
starts new text.
Test: clicking_another_panel_stops_typing_into_text, with the Type tool
and with an edit started by command: Character > Faux Bold keeps the edit,
its selection and typing; clicking the solid's Timeline row ends it,
selects the solid, typed characters leave the text unchanged and Space
plays; an empty Type-tool layer is removed. Fails on main.
