The wikitext: Foo [[File:Frisian flag.svg|simple caption|thumb]] bar renders a <figure> with a caption, but the wikitext: Foo [[File:Frisian flag.svg|simple caption]] bar renders an <a><img> with no caption. MediaWiki's PHP parser renders the caption as the title attribute of the <a>. If the caption of an inline image contains wikitext, it's distilled down to plain text. For instance, try [[File:Frisian flag.svg|'''rich''' [[text]] in <table><tr><td>the</td><td>caption</td></tr></table>]] for instance. For non-inline images, Parsoid behaves totally correctly, including the rendering of captions containing wikitext.
Just setting the title attribute should be relatively straightforward (using tokensToString()). Making it editable in a way that handles non-text original content will need some thought though. Maybe HTML in an attribute, which we considered elsewhere?
Since this is pretty rare, we should probably simply shadow the plain-text attribute and support plain-text editing only. This would still preserve non-text captions when they are not edited, but will convert to plain-text caption with the first edit.
We are exposing the caption as editable HTML in data-mw. The title attribute for viewing can be set from that in a post-processing step. Please reopen if there are still issues with inline captions.
