I can reproduce this in 4.17 by trying to do a Find/Replace from the Product Configuration Editor's Source page's Edit menu.
I can recreate this too using previous comment.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
Cannot reproduce anymore with Eclipse 2022-09
