I don't think you'll be able to fix the scroll bar on desktop without moving the page into its own scrolling container.
I've been meaning to do this for a while as it will help mitigate ios iframe scrolling issues and help with accessibility virtual cursor placement, but it is a huge change.

Is it possible to add overflow:hidden to html tag on popup open and remove on popup close.

[oliverfoster]

Nope, the scroll position will get lost. Seems to work in chrome and ie11... (I'm not sure why I thought it would jump back to the top) although the content will jump to the right because the width of scrollbar goes missing - on browsers with unfloated scrollbars.

Could you test out #2169? See if that helps?

[NayanKhedkar]

Sure.

[NayanKhedkar]

It fixed the problem. 👍
