Two double scrollbars on some messages, and unable to scroll a particular email message
Tested with Evolution 3.48.2-1.fc38 (Wayland GNOME session), with this message: evolution_broken_scroll_message_-symposium__anonymized.mbox
...I am encountering this issue where not only there are two scrollbars (particularly noticeable if you turn off "Overlay scrollbars" in the GNOME visual accessibility settings):
...but scrolling up/down with the mouse wheel is impossible; nothing happens when you do that.
