Webforms behaviour notes

@JenniferQ (moving this away from a thread that was meant to be about Collect issues)

versions:

I did see that issue and wondered if it was related, but thought that it was primarily around editing submissions with version changes affecting the file in an image question, whereas what I was seeing was the image display against a select working and then not working, and only being restored if I uploaded a file that is "different" (i.e. reuploading the identical file doesn't fix it).

Additionally, the form was always in draft, there were no submissions, all the behaviour was observed while completing the draft form testing.

I don't know exactly what caused the images to stop appearing either. First one broke, then two more (the latter two I had replaced the original image as I uploaded the wrong files initially). It appears to be independent of version but maybe time based (related to files being moved to S3?).

I opened the 2026-07-20 draft that added the 'new' options, and now all images are broken (two days ago the first 3 options were broken but the newly added ones were ok). There has been no version change since my earlier post that added the 'new' options.
