I did an experiment where I went into WYSIWYG mode and back to HTML mode without editing anything, and the result was what you got. Instead of FIGURE tags connecting images and captions, each image and each caption was in its own P tag, and the FIGURE tags were just gone. So, I should put up a confirm box with a warning when someone tries to switch to WYSIWYG mode when there is content that might be damaged by it.
That'll do, at least until the sections with such content can automatically activate the Source button (and manually deactivating it generates that warning).
Reminder: This happens to Interactive Diagrams as well.
