Did you actually try to edit it?  Not just typing "abc" at the beginning 
of the line, but (as is described on the web page you pointed to) moving 
to the end of the line and performing editing operations there.

Nobody is saying that there is no bug here.  I was only pointing out that 
the bug is not "in Emacs", it is in the fontification routines of a 
specific mode.  If you turn fontification off, you will see that Emacs 30 
behaves much better than Emacs 28.
