data:text/html,<input type="checkbox"><input type="checkbox" style="height:auto"> Expected results: Checkboxes are the same height/width Actual results: The second checkbox is smaller Only applies to themed checkboxes/radio buttons.

Is this still an issue?

Yes.

So what height would you expect then? The current height just comes from forms.css, no? Note that on Linux this doesn't seem to be a problem, by the way...

I think the current height comes from nsFormControlFrame::GetIntrinsicHeight: return nsPresContext::CSSPixelsToAppUnits(13 - 2 * 2); Subtracting 2 * 2 makes sense for non-themed buttons because they have a border-width of 2px. Themed radios / checkboxes however have their widget border set to 0 on OS X and to something that comes from the system on Windows and Linux. I think we should set the widget padding to 2px on all platforms.
