Browser issue Firefox-Specific Overlay Bug

[Alien]

In latest Firefox (23.0.1), including default style on test 1.2.1 site and reproducible here at xenforo.com

Some buttons are not aligning properly...

One example of this overlay occurs when you try to add an image to a post in a thread.

Look at the cancel button in the screenshot below:



It's even more noticeable if you don't use boxshadow or use custom styles.

This doesn't occur in Chrome at all.

Unfortunately this is roughly a well known Firefox issue. It's possible it's regressed more recently.

See these few links:

Rats.

Does the workaround mentioned at the bottom of the page here:

https://bugzilla.mozilla.org/show_bug.cgi?id=697451

...work in this case? Since this issue isn't likely to be resolved in the near term, it might be worth a workaround?

I did try it and it may have resolved the issue, but it changes the button size fairly significantly so it's not something we would likely do in the short term.
