Adding a Marker to an Audio Clip and then Removing It Still Forces File Re-Write

Using Audition build 24.0.3.3 on Windows 10 Pro 22H2

When I'm working in an Audition multi-track session, I'll sometimes accidentally hit the "M" key to leave a marker when I have a clip selected. Usually I either meant to put the marker in the project and not the clip, or meant to hit a different key or combo, but now I have a marker INSIDE the clip. Even if I immediately UNDO and the marker is no longer there, Audition still insists, the next time I save my project, on re-writing the clip to disk. This is incredibly frustrating because A) nothing has materially changed about the file, B) it takes a long time to perform the save on a 2 hour audio block and takes me out of my flow, and C) I'm usually working in MP3, meaning it's re-saving in a lossy format and losing some data.
