iPad-specific sidebar issue

Hi! I found an iPad-specific sidebar issue in FluentCommunity.

On iPad in portrait mode, the sidebar opens as an overlay. If the sidebar content is longer than the screen and I try to scroll down inside it, the page behind the sidebar scrolls as well, which causes the sidebar to close.

In landscape mode, the sidebar stays fixed on the left and works normally.

Tested in both Safari and Chrome on iPad, with the same result.

It seems that scrolling inside the mobile/tablet sidebar is propagating to the underlying page instead of being contained within the sidebar.
