@cyan: Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note : 
1. Issue cannot be reproduced on Linux(14.04 LTS) and Mac(10.13.1, 10.13.6, 10.14.2) OS.
2. Tried per revision bisect on Windows OS but unable to perform the same since getting "RuntimeError: We don't have enough builds to bisect" error, hence, providing chromium bisect.
3. On Win 7 and 8 OS , the above issue is reproduced only after clicking the 'Undo' button on the infobar after applying a theme.
