Panel changing color with third-party theme and "Auto hide panel w bookmarks" enabled

[Shanti09]

This may be caused by Chromium changes.
We will try to figure it out, whether this is a bug or normal behavior.
Auto-hide bookmark bar has different Window structure from normal bookmark bar, though they look the same.

Thank you, after update, this problem has been fixed, 
I just updated to version 4.2.10.169 and get kind of similar bug. Would you please check.
Thank you so much for your great work.
