Summary: Regression: Weird scroll bar is seen in pdf's on adding PDF viewer extension. (was: Regression: Weird scroll bar in pdf's on adding PDF viewer extension.)
Does this work property without the extension installed? Is this an internal PDF viewer issue, or a problem caused by adding the extension?

If you are using an external PDF viewer extension, shouldn't you report this bug to them? How is this a ReleaseBlock-Stable?

Issue is seen only on adding  PDF viewer extension. As it was an recent regression issue marked it as Release Block Stable. 

Please feel free to remove if not the case.

Thanks!
It looks like you have overlay scrollbars enabled via the about://flags

jbanavatu@ can you confirm this?

When I enable this I see the scrollbars as you mention. I don't believe overlay scrollbars is shipping yet and this is an experimental feature so we should be able to drop priority and release block stable as I believe this is working as intended.

Overlay scrollbars was enabled in M57 and now it is disabled in that branch. Closing issue as it shouldn't happen anymore.
