MD Settings: Fix Search tooltip arrow obscuring letters

The arrow for the search bubbles is rendering on top of the text. This
blocks parts of the letter for letters like 'y' or 'j', when the tooltip
is in the "above" position.

This CL adds a z-index to put the arrow behind the letters, which is the
same solution that Old Options used.

M54 is already in Stable now, may be we could take the fix for M55.Lopping to folks who are involved.

A friendly reminder that M55 Stable is launch is coming soon! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP so it gets enough baking time in Beta (before Stable promotion). Thank you!

Also due to Thanksgiving holidays in US, please make sure fix is ready and merged to M55 latest by 5:00 PM PT Friday, 11/18/16 (sooner the better).

Hey guys, this does not need a merge, since MD Settings isn't released yet. The fix will go out as normal along with M56.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-55; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-55 label, otherwise remove Merge-TBD label. Thanks.

I removed the merge and M55 labels. No need for m55 merge
