From the above change log, got a blink roll. But unable to open that blink roll link. Hence, was unable to find a suspect from the chance log.

eseidel@ - Could you please help us in assigning it to the right owner.

Thanks...!!

Looks like we reserve space on the wrong side for floats. Doesn't happen with overlay scrollbars.

Has been broken for two and a half years without being noticed so downgrading priority to 2.

Assigning to Sanjoy so I can take it off my queue. Pretty sure this is from your CL Sanjoy, let me know if you think otherwise!
