Weird behavior when moving a maximized tab

When moving a maximized tab it behaves weird, I don’t really know how to put it in words…

You can see a video demonstration here: http://youtu.be/geRAFiHIvIc

Comodo Dragon 33.0

Windows 8.1 update 1 64bit

UAC on

Installed on C:\Program Files (x86)\Comodo\Dragon\

Administrator account

Google Chrome v34 installed and it does not behave the same, whenever I move a tab from maximized state it reassumes that maximized state when I drop it.
