The select does not resize. But for some reason, a reflow of the HTML is triggered, and DOM Inspector shows the containing table to go off the screen to the right. Reproducible: Always Steps to Reproduce: 1. Choose another value in the <select> menu Actual Results: A horizontal scrollbar shows up in the application window, as if it is resized to be too wide for the screen. Expected Results: No change should occur in the reflow. It also occurs on Windows.
Happens in FF 1.5/Win as well.
Confirming with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051202 Firefox/1.6a1 ID:2005120206. Changing OS to all.
Also happens in Camino. -> Core
Interestingly, the redraw also occurs if you open a link on the page in a new tab.
Correction, if you have no tabs open, it redraws with the scrollbar if you open a link in the new tab, assuming you have 'hide tabs when there is only one tab' set.
Okay, this has nothing to do with <select> per se. In fact, you can reproduce it with the example at: http://www.thomasoandrews.com/examples/mozilla/sizing/nonselect.html If you resize your window without changing the window's width, just its height, you can induce the bug. That's why creating a new tab in the previous comments showed the problem - it amounted to resizing the window without changing the width. You can do this by manually resizing, or you can show or hide a toolbar (which resizes the height but not width of the display window.) For some reason, this isn't 100%, but if it doesn't work by showing a hidden toolbar, you can probably reproduce it by hiding the toolbar.

I can no longer reproduce this with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20070102 Minefield/3.0a2pre ID:2007010204 [cairo] My guess is this was fixed by the reflow branch landing.
