Affects doom/browse-in-other-project, doom/find-file-in-other-project,
+default/search-other-project and
+default/search-project-for-symbol-at-point.

this update the current project would be the first highlighted
candidate, which doesn't make much sense when you're invoking a command
for searching *other* projects.
