Please check the example — the row filter shows values that exist only in the lookup, but not in the data grid (e.g., "apple" and "kiwi" are missing).
Expected behavior:
The row filter should display all values that exist in the grid and by which the user can filter.
In my case, the lookup will always differ from the real data.
I set syncLookupFilterValues to false as recommended in the documentation, but it didn't help.
