While a Type tool edited text, a click on blank canvas ended the
editing and also placed new point type at the click. Area Type and
Type on a Path did the same with a click on a path.
Such a click now only ends the editing. The typing session is
committed, empty point type that a click placed is discarded as before,
and the Type tool in use stays active; the next click makes new type.
The same applies when the editing began with a double-click from a
selection tool. A click on other type still edits it at once, and a
drag that draws an area-type frame still makes the frame.
