Reproducibility: Always Seen on build 2002032709, but it's probably been around a while. Steps to reproduce: 1. Open any page with comboboxes (ie bugzilla query) 2. Use text zoom to change to an extreme setting (CTRL++ or View->Text Zoom->Larger several times) 3. Observe combo boxes have not changed height. The problem is not very visible when you open a page with normal font sizes, but it's much worse if you set your fonts unusually small before opening a page with comboboxes. This can force combobox content to be impossible to read until you select the control. I came across this problem when I accidentally used the new mouse scroll wheel setting to change the font size to a very small setting, then reloaded the query page. When I restored the font to a normal size, all of the comboboxes stayed at the small extremely small height. If the user doesn't realize they can click each box to see its contents, they might reload and lose any form information they've entered. Could this also be an accessibility issue?
