           Summary: HTML listbox is not resized horizontally when zooming
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: PC
               URL: http://www.htmlcodetutorial.com/forms/_SELECT_MULTIPLE.h
                    tml
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P3
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: artem.ananiev at sun.com


HTML listbox is defined using <select multiple=".."> tag. When a page with
listbox is zoomed in/out (Ctrl+'+' or Ctrl+'-' in Safari on Windows), the
listbox font is changed, and listbox vertical size is adjusted. However,
horizontal size always remains the same regardless of the font size, and no
horizontal scrollbar appears. This leads to some options to be partially
invisible in the listbox. If user later clicks on the listbox, it is expanded
horizontally according to the current font size.

Steps to reproduce the problem:
1. Load the URL: http://www.htmlcodetutorial.com/forms/_SELECT_MULTIPLE.html
2. Find 'produces this' listbox on the page. It should contain 5 items, and
listbox width is adjusted to the longest item.
3. Press Ctrl+'+'.
4. Listbox font is increased, listbox height is adjusted according to the font,
but listbox width remains the same. The longest listbox item is truncated.
5. Click on the listbox. It is immediately enlarged, so its width again
corresponds to the longest item.

If you see the described behavior, the bug is reproduced.
