Description:
If I do:

<gallery caption="foo {{some template}} bar">
Image_PlaceHolder.png|Caption of the picture
</gallery>

... the caption isn't expanded at all and displays as "foo {{some template}} bar"

If I do:

{{#tag:gallery|
Image_PlaceHolder.png{{!}}Caption of the picture
|caption=foo {{some template}} bar
}}

... The caption is expanded but HTML code is escaped so it displays as "foo <span><div><sup>[etc.] bar"

An example is provided here: http://fr.wikipedia.org/w/index.php?oldid=70852029

Expected result: The caption should be expanded, ideally in both cases; sadly I presume it would require to add a new syntax, because of the first case.

In order to prove the usefulness of the asked fix:

• there is no problem in putting HTML elements into a <caption> element[1][2], in case <gallery> would use this element in the future
• on the French Wikipedia we are working on making accessible abbreviation templates, using <abbr>[3], so that their result is readable by speech synthesizers.
