The bookmarks UI changed recently in a mostly good way.
And… it seems that the behavior silently(!!!) changed as well.
Previously, if I set a reminder on a bookmark, the bookmark was cleaned out after the notification (per an Easter egg setting).
Now… that doesn’t seem to be the case? I noticed the other day that reminder bookmarks I’ve set since the UI change are still in my bookmark list, even though I’ve already gotten the notifications.
I set some tests Friday. Bookmark alerts seem a bit resistant to being marked ‘read’, but once they finally give in, they do disappear from the list as they should.
