render bug on Firefox when iframe is hidden (maybe FF bug?)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open http://marianoguerra.github.com/json-edit/eflang/renderbug.html on 
firefox
2. switch to second of third tab
3. see the panel doesn't have the correct width (or any widget inside, all 
would be collapsed to minimum width)

What is the expected output? What do you see instead?

expected to see the panel with the correct width, as seen on Chromium or Opera

What browser are you using?

Firefox 17.0 and Firefox Nighlty

Please provide any additional information below.

it may be a Firefox rendering bug since it works on other environments, but 
just checking here to confirm or to find a workaround it.

This is a rendering bug in Firefox: 
https://bugzilla.mozilla.org/show_bug.cgi?id=528969 Clearly they won't be 
fixing it any time soon.

The work around is that when you show the iframe, call:
Blockly.mainWorkspace.render();
