Cider's eval and load remove foreign overlays and fringes #2018
Description
When placing a temporary bookmark (bm package) on a def, then executing any of cider eval or load commands the bm bookmark is removed.
This is a relatively recent problem. Previously cider would only shadow fringe marks with its own cider-fringe-indicator, but now it completely removes those.
