Bug 56170 – Select list/combo box selection not changed if the option clicked was highlighted beforehand by typing its first letter.

• Status: UNCONFIRMED
• Component: Forms

If you:

1. Visit a site with a select list / combo box, such as http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_option

2. Click the arrow next to the box to display the dropdown.

3. Type for example 's', causing the highlighted option in the dropdown list to be "Saab".

4. Click the "Saab" option from the dropdown.

Then the combo box's selection is not changed to "Saab" as you would expect, and remains at whatever was selected by default when you first loaded the page (in the site above, Volvo). You can move the mouse to highlight another option before clicking "Saab" and the results will be the same. However, clicking any other option in the list that was not highlighted by the key press -- Mercedes, Audi, etc. -- will cause the selection to change as is expected.

You can replace 's' and "Saab" above with 'm' and "Mercedes" or 'a' and "Audi" and the result will be the same.

Broken for me in Chrome 10 and Safari 5.0.4; works properly in Firefox 4, Opera 11, and IE9.

I cannot reproduce this on Mac, so could be Windows only.

I can reproduce in Safari 5.0.4 on Windows.

I tested it on Chrome under OSX 10.6, and wasn't able to reproduce.

This was most likely a side effect of the bug filed at https://bugs.webkit.org/show_bug.cgi?id=53023 which should be fixed.
