When editing a page which has an image with table data in its caption, the table is dropped (only its closing tab is kept). The rest of the caption is dropped as well. Test edit: https://hu.wikipedia.org/w/index.php?title=Vall%C3%A1s&diff=13696305&oldid=13696296 You don't need to interact with the image in any way for this to happen, just edit the page, change anything and save.
Horrible, relatively-rare case for Parsoid, is the use of wikitext tables inside image captions. Currently, the following wikitext: [Start] [[Image:Foo.jpg|thumb|200px|This is an example image thumbnail caption with a table {| ! Foo !! Bar |- | Foo1 || Bar1 |- | Foo2 || Bar2 |} … and some more text.]] [End] … turns into the following output from Parsoid: [Start] <figure typeof="mw:Image/Thumb" data-parsoid="…"> <a href="./File:Foo.jpg" data-parsoid="…"> <img resource="./File:Foo.jpg" src="http://upload.wikimedia.org/wikipedia/commons/thumb/0/06/Foo.jpg/200px-Foo.jpg" height="131" width="200" data-parsoid="…"> </a> <figcaption class="mw-figcaption" data-parsoid="…">} … and some more text. </figcaption> </figure> [End] … whereas nominally it should be (generated using an HTML table rather than a wikitext one, which seems to work fine without DOM diffs from VE end): [Start] <figure typeof="mw:Image/Thumb" data-parsoid="…"> <a href="./File:Foo.jpg" data-parsoid="…"> <img resource="./File:Foo.jpg" src="http://upload.wikimedia.org/wikipedia/commons/thumb/0/06/Foo.jpg/200px-Foo.jpg" height="131" width="200" data-parsoid="…"> </a> <figcaption class="mw-figcaption" data-parsoid="…">This is an example image thumbnail caption with a table <table data-parsoid="…"> <tbody data-parsoid="…"> <tr data-parsoid="…"> <th data-parsoid="…">Foo</th> <th data-parsoid="…">Bar</th> </tr> <tr data-parsoid="…"> <td data-parsoid="…">Foo1</td> <td data-parsoid="…">Bar1</td> </tr> <tr data-parsoid="…"> <td data-parsoid="…">Foo2</td> <td data-parsoid="…">Bar2</td> </tr> </tbody> </table> … and some more text. </figcaption> </figure> [End]
This is a tokenizer issue. The table is not tokenized as such, likely because syntax stops prevent a pipe from being matched. If this image is not modified by the user it should still round-trip correctly, but on modification the table would be lost.

The table is lost even if the user does not interact with the image in any way. See [[hu:Vallás]] - the image caption gets garbled as soon as you open the article for editing.

The corruption even if you don't touch it is a bug in VisualEditor related to munging the captions of images, which we're fixing today; sorry for that.
