Submitting and then reverting so that we can merge to M46 to follow merge
request process.

Manually tested that syncing back to around M46 branch, with this change caret
is missing in test case #6 from http://crbug.com/523969 and with the change
reverted it is present.

Also on ToT caret is present both with and without this change. With this change
reverted there is however an extra one pixel to the right of the caret (so 2
pixels of whitespace where there would ideally be one for nice visuals). Since
I'll be quickly reverting this change from ToT this is fine.
