Redo button still active after all steps are redone in version 6.24.309.1.rc3

This happens in version 6.24.309.1.rc3:
When you edit a file, Undo all, then Redo all (by press the Undo/Redo buttons), the Redo button is still available, unless you select some text in the file, by then the Redo button turns grey and becomes unavailable.
Try the following as an example to see the problem:
Open a text file, key in some words in different lines.
Undo all by press the Undo button.
Redo all by pree the Redo button. -- Now you can see the Redo button is still in active color, but pressing on it has no effect.
Double click on a word to select it, the Redo button turns grey (normal status).

I confirm, it's a bug introduces with version "Notepad3 6.23.1117.1 rc"
ref. issue #5051
ref. issue #5053

• [1117.1]- Reduce window flickering
• [1117.1]- Fix cut last line.

Additionally, the Undo/Redo workflow is not correct (Redo is only possible when all Undos are completed). 🤔
