1) Check, if problem exists in current nightly version from http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/firefox-21.0a1.en-US.mac.dmg
2) If yes, attach to this bug simple testcase showing the issue

Phoenix, you can put the testcase together pretty easily from the link, no?  I'll attach it in a sec.

It's not clear to me what the right behavior here is per spec, for a table...  In particular, the overflow property does NOT apply to tables per spec as far as I can see, so there's no obvious reason the caption would be hidden.  But the clip should work, I would think...

That sounds right. ::-moz-table-outer should probably inherit "clip".

Comment 5

[Boris Zbarsky [:bzbarsky]]

Attachment: Apply clip to outer table frames as needed.

Adding dev-doc-needed, it will be a good opportunity to document ::-moz-table-outer on the MDN.

Comment 7

[Boris Zbarsky [:bzbarsky]]

The current situation with dev-doc-needed is that it's a no-op.  If you think there should be docs, you need to find someone (possibly yourself) to do them....

Comment 8

[Jean-Yves Perrier [:teoli]]

Yep, that's the idea. Dev-doc-needed appear in our tracker tool (even a long time after the release with the fix). Though we don't have the resource to take care of all of them, they still appear. I try to take care of all CSS-related dev-doc-needed once every month or so (depending of my time).

Also use the dev-doc-needed/complete list for a release in the process leading to the Release Notes (via the Aurora meeting).

And this bug, once fixed, is good candidate for our "Site compatibility for Firefox XY" and "Firefox XY for developers" page too. (Though the inclusion in these is not enough to clear the flag, ddn/ddc bugs are used to fill these pages too)

So dev-doc-needed, even if it doesn't lead to the proper doc to be automatically written, has some useful purposes ;-)
