Buttons to be editable, toolbar options to be clickable.
Button text at some point locks up, and cannot be edited. Toolbars do not work at all.
The text editing and toolbar issue are both in Chrome Version 80.0.3987.87 (Official Build) (64-bit).
Text editing for buttons works in Firefox, but the toolbar is still broken in Firefox 72.0.2 (64-bit).

#painpoint. #manual-testing #user-report if applicable.
This issue has also been reported in vanilla CoBlocks godaddy-wordpress/coblocks#1252 and has a fix underway (godaddy-wordpress/coblocks#1329).
It doesn't mention the issue of not being able to edit text on Chrome, but I suspect fixing the z-index issues will address this too.
I tested godaddy-wordpress/coblocks#1329 locally and was unable to reproduce the text editing issue in Chrome 馃憤
Closing since it's been addressed in core CoBlocks plugin
