Search engine drop down closes when I change search engines by pressing Up/Down
>>> My Info: Win7_64, Nightly 48, 32bit, ID 20160326030430 STR: 1. Open about:preferences#search 2. Expand search engine drop down 3. Press Down key AR: Search engine drop down collapses ER: Search engine drop down should stay visible This is regression from bug 1122618. Regression range: > https://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=861971c670e1fe27c8bf43833831d7ce17b46f00&tochange=503ebfe13cd2f079829f4a4c8b7e860b4989403f
Regression from 46, let's track this for 48/49 and find an owner for the bug. Wontfix for 46/47 as we are a couple of weeks away from the 47 release now. Florian, can you take a look here and help find an owner, since you were the reviewer on bug 1122618? Thanks!
I can't reproduce on Mac. Someone else tested on a Linux nightly and couldn't reproduce either. This may be Windows specific.
I can reproduce on Windows. On Mac when the user moves through the list in the drop down using up/down it highlights the new row but only selects it after pressing enter. On Windows it changes the selection immediately, which causes this code https://hg.mozilla.org/mozilla-central/rev/503ebfe13cd2#l1.33 to run and destroy the drop down to rebuild it.
I'm going to test this patch on Windows before requesting review, but I'm confident it should fix the problem.

Comment on attachment 8761155 [details] [diff] [review] Fix A reluctant r=me as a wallpaper fix, but why does scrolling through that list fire engine-current on Windows but not elsewhere? Can't we just make it not do that? If not, please include a comment before the if() explaining why we need to check this...

If not, please include a comment before the if() explaining why > we need to check this... I assumed it was an intended platform specific behavior. On Windows when going up/down in a menulist the highlighted row is selected immediately. On Mac when using up/down, there's a light highlight on the new row (similar to what we have for an hovered row). I couldn't find code doing anything specific to Windows when looking at the menulist related code, but to be honest I didn't spend much time searching for it, because the patch doesn't seem bad to me: it's an optimization (we avoid rebuilding the whole list of engines) for the general case (ie. when the change has been made from the pref window, which should be the case most of the time).
