Using v2.93, when editing the
TITLE tag of a MP4 file with a generated chapter list, the previous title value is used for the chapter name.
For example, if the file was tagged with
TITLE as "Original Title" and I change it to "New Title", the generated chapter marker is named "Original Title" when the file is saved. If I then change
TITLE to "Another Title", the chapter is now named "New Title".
