Yeah we are going to sort this out, bear with us, so sorry it is taking so long.
It is very hard to feature detect this problem we have a few options at hand
-
Instead of putting a placeholder of
uploading ...we swap our placeholder to use … -
Use a “regex” replace that is not sensitive to this
-
Disable execCommand as the mechanism for inserting text in this instance (it is pointless anyway, given pasting the image will corrupt undo stack anyway)
-
Just have execCommand stuff behind a site setting, disabled by default
or a combination of some of these.
It is on Davids list, and we are tracking.
