Improper handling of zero length matches

[SiouWang]

OS: Mac OS Monterey 12.4 NotepadNext: Qt version 5.15.2.

When i using the "find" function in "regular expression" mode, i can not find anything.

There is some words like this: aaaaaa bbbbbb ccccccc I want to add the "," to the end for each line. In "Notepad++" i can use the "$" to find it , and use the "," to replace. but a single "$" is not work in notepadnext.

I can reproduce it as well. Looks like it is related to zero length matches.
