Bug 11852 – REGRESSION: <select disabled size="5"> listbox cannot be scrolled

• Status: RESOLVED
• Resolution: FIXED
• Component: Forms

[Jesse Ruderman]

This HTML results in an unscrollable listbox, so you can't see what the last few options are:

<select disabled size="5">
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
<option>Option 4</option>
<option>Option 5</option>
<option>Option 6</option>
<option>Option 7</option>
<option>Option 8</option>
</select>

Bugzilla 3.0 was going to use <select disabled size="5"> for CC lists for logged-out users, but that will probably be changed before the release, so that users with the buggy versions of WebKit can see who is CC'ed.  And IE users, if there are still any (IE has a similar bug).  See https://bugzilla.mozilla.org/show_bug.cgi?id=364065.

This bug happens on WebKit trunk, but not shipping Safari on Tiger.

always pass mouse press events to scrollbars

No layout test, clicking scrollbars using DumpRenderTree eventSender does not work (view is always null in passMouseDownEventToWidget in EventHandlerMac.mm).
