TinyMCE and figcaption

[DavidJessurun]

Hi all,

I'm using the latest version of CMSMS and a recently installed, up to date TinyMCE.

Here's the problem:
When I type <figure><img ...><figcaption>...</figcaption></figure> by hand, it stays.

When I add code from a TinyMCE template through the template plugin, it's stripped.

I tried adding:
valid_children: "+figure[figcaption]",

and:

extended_valid_elements: "figcaption"

No dice.

Anyone know how to fix this?

TIA!
