Description Jeff Fortin 2023-04-28 13:08:04 PDT

Tested on Epiphany 44.2 + WebKitGTK 2.40.1 from Fedora 38, in GNOME's Wayland session.

1. Go to https://tweetdeck.twitter.com/
2. If not already logged in with a Twitter account, scroll just below the main paragraph, and click "Go to legacy TweetDeck" (because at least there we will have a somewhat consistent thing to test with, until the new ownership destroys that)
3. Add a bunch of columns (searches, lists, whatever) so that horizontal scroll is possible/needed
4. Try to grab the super thin scrollbar at the bottom of the window

Result: impossible to click/drag/grab it with the mouse, scrolling (and revealing the scrollbar) is only possible using Shift+scrollwheel in an empty area (ex: an empty column, or a column header). It works in Firefox and Chromium, however, where hovering near the bottom area reveals/expands the horizontal scrollbar which you can drag very smoothly (unlike in bug #220085).
