SELECT elements with min-width:100% are not computing their initial widths
correctly, and are not resizing when certain reflows occurr. I am assuming they
should behave the same as text inputs.

Reproducible: Always

Steps to Reproduce:
Test Case 1 Part A (top) shows three elements with min-width:100% (select, div
input:text).

1. Make sure window is not maximized.
2. Note that all three elements are full width of window.
3. Resize window horizontally.
Actual Results:  
Select does not resize as the other elements do. The select's with seems fixed.

Expected Results:  
Select resizes similar to other elements.

Changing text size via the browser menu forces the select to resize.

Although this testcase does not demonstrate it, I have observed that bringing up
the context menu will force the select to resize also, however this may be a
table reflow bug.

Part B (bottom) has a select in a table. Again the select does not resize, and
when the text size is changed the width is often not truly 100%, there are gaps
on the right side.

Confirmed.  The behavior (of testcase part a) is the same at least as far back
as September 2004 builds; so this is not a recent regression.
Part B of the testcase should probably be submitted as a separate bug, and this
testcase minimized.

The first part is probably due to the size caching select does.

Seems fixed by reflow branch landing
