(1.25) Bug: opening a new tab on a maximized window makes window larger
I've been experiencing this bug for a while now that makes a maximized window (9 pixels) larger, occupying the top part of my taskbar's space, when opening a new tab. When it happens, the window remains maximized (with the restore down button shown).
It seems to only affect the new tab. When I switch to the other tabs, the window's size corrects itself.
Here's a screenshot of the bug with the taskbar made transparent via Start10:
