Patch #26 works but does not track keywords without results.
I created the layout with 10.2.2, updated to 10.2.3 (still working) and after update to 10.2.4 it broke.
The steps to reproduce contain the minimum steps to reproduce the problem, the mentioned module is not necessary.
I tried to revert the changes introduced in #3398196 and it started working again.
