filter is not rendered correctly if you open two layers and then switch to the second

[ralfherberer78]

tested with fresh .josm directory. Does also happen with JOSM version 9900.

What steps will reproduce the problem?

Have a filter to "modified" elements status active, load two layers (which each have some some modified objects) from .osm files, select the green "edit" tick in the layers box of the second (currently not active layer).

What is the expected result?

the second layer is shown in the map and only modified objects are shown.

What happens instead?

the second layer is shown in the map and all objects are shown.

Workaround: disable/enable the filter or the layers or just drag the map a bit.

Please provide any additional information below. Attach a screenshot if possible.
