684456 - Switching tab using CTRL+PgUp/PgDown also scrolls <select multiple>

Status: NEW

(Core :: Layout: Form Controls, defect)

STEPS TO REPRODUCE
(0. make sure you have a few tabs open)
1. load data:text/html,<select multiple><option>x<option>x<option>x<option>x<option>x<option>x<option>x</select>
2. click on the first item, note that it is displayed with a focus outline
3. CTRL+PgDown then CTRL+PgUp

ACTUAL RESULTS
The first item is still selected, but the focus outline moves down to the
last visible item; repeating 3 moves it again, this time it also scrolls
the list to show the new item.  (Similar problem occurs if you click on the
last item in 2, and then CTRL+PgUp followed by CTRL+PgDown)

So it appears we let both the tab-switching and <select> handle the
same keyboard event.

EXPECTED RESULTS
CTRL+PgUp / CTRL+PgDown should only do tab-switching.  Not affect the <select>.

Bug occurs in 9.0a1 and 4.0 on Linux64

Or vice versa, I don't really know which one is intended.
