fix: support collaboration in bound text (#4573)

* fix: support collaboration in bounded text

* align implementation irrespective of collab/submit

* don't wrap when submitted

* fix

* tests: exit editor via ESCAPE instead to remove async hacks

* simplify and remove dead comment

* remove mutating coords in submit since its taken care in updateWysiwygStyle
