Comment 7 Justin L 2023-10-13 16:26:18 UTC
The problem here is that after the undo, the cursor has moved out of the text body, and into the comment.

Comment 3's bibisect result is not correct. The difference is that prior to my fix, you couldn't (easily) get the cursor behind the comment. So your first backspace was deleting the x, not the comment, and the second backspace did nothing.

The original steps to reproduce are overly complicated. Only a single backspace is necessary - the backspace that deleted the comment (and therefore only one undo).

Steps to reproduce:
-place the cursor after the x
-press backspace (which deletes the comment)
-press Ctrl-Z (to undo - the comment returns and the cursor is now in the comment)

Prior to my commit, use DEL instead of BACKSPACE to get the same result.

The cursor change is coming because the comment display "area" is appearing and disappearing (but of course not going away when track changes is showing - in that case the comment stays, but is crossed out).

The disappearing/reappearing comment area started in LO 6.3 (backported to 6.2.0) with commit 32902f66e7749b2d06d13f50416be5323a0c0ea9

bisecting in LO 6.2 with experimental mode turned on points to the commit that hides the comment margin when the comment is deleted.

    sw_redlinehide_4b: consider the comments in the margin

I assume what is happening is that normally the comment margin shows up when the first comment is created, so it is assumed that the cursor should be placed inside the comment. (Indeed, if we add a second comment to the provided bug document, the cursor is not moved when following the steps to reproduce.)

Indeed, the same behaviour is seen when turning off View - Comments, and then turning them back on.

Calling this a regression is not really appropriate. It is a consequence...
