Attachment: Testcase showing widening select box (when in a table)

Made a simplified testcase of provided URL.

Cannot pinpoint the cause of the 'unlimited growing' bug from that site, but
working on it. This testcase shows the 'small one-off growth' in width when new
selection made.

Attachment: More accurate testcase.

The new testcase more accurately demonstrates what appears to be 2 different
behaviours depending on where the SELECT dropdowns are located (in tables or
not in tables).

This appears to be caused by the css height declaration.

Unlimited growth, and one off small growth issues still occur if style is set
inline.

i.e. These still occur when using <select style="height:20px;"> (in addition to
when <select class="textbox"> is used (see testcase from comment #2 for this))
