How to get rid of "bookmarks" in designer?

The designer bookmarks every single database you touch with designer, even if you were just in it for 5 seconds to check for something.

All these bookmarks get in the way of finding easily bookmarks you actually care about.

This was of course an issue in earlier designer releases, but I am wondering if 8.5 might have introduced a way to stop this. Or, at the very least, introduced a quick way to clear them. Currently I have to go through this huge list one by one by one by one by one by one by one by one by one – to clear it.
