ContentBox - Getting width and height of a hidden element?

[guest]

Not sure whether this should be an enhancement or a defect,

I've just starting playing with 0.9 and there seems to be a lot widgets using dojo.contentBox, the problem is hidden elements return a height of 0. This is correct but can cause problems for some widgets.

Is there a function in dojo that allows getting the width and height of an element "as if it were not hidden"?

I'll an attach an example / test case of the problem for the progressBar

Usage of dojo.ContentBox? on ProgressBar? doesn't provide expected result when contained in hidden block

As for ProgressBar?, #2803 has been filed to remove javascript sizing from that widget (for this reason). Actually none of the form widgets should do javascript sizing. The layout widgets do javascript sizing, but they should never be hidden, except for the hidden tabs in a TabContainer/StackContainer?/etc., but those cases are also handled correctly because we don't do sizing until the content is visible.

So we aren't planning to make the change the way dojo.contentBox() works, but it shouldn't cause an issue for the widgets, as per description above.
