I’m adding cue points to a video, but the cue point icon is not displaying on the timeline, and after adding a cue point it doesn’t actually appear in the cue point list. So, I have no way of deleting or adding them.
What are some possible causes of this that I should be considering? I’m using Firefox browser version 115.9.1esr (64-bit) for Mac
EDIT: confirming that this appears to be an issue with Firefox, or at least the ESR version I;m using. The cue points are displayed properly in Chrome 103.0.5060.134 (Official Build) (x86_64) for Mac.
