Item list looses filter

[aurelio1]

Issue

I am in the Item list and do the following:

1. enter a filter, eg. "airQ_" to show all items containing airQ_
2. I go into an Item
3. In the view of the single Item, I press "back" in the upper left corner
4. the Item list appears with "airQ_" in the filter entry box, but the entries are not filtered

Expected behavior

I would expect that the list is still filtered when I go back to the Item list.

Steps to reproduce

Additional information

[eikowagenknecht]

Same here. One addition: When going back the list first is filtered and then after half a second or so it is apparently refreshed and unfiltered. Also: Going into the search bar and pressing enter doesn't fix it, only removing and readding a character leads to filtering it again.

This does apparently only affect the Items view, Things and Pages for example behave correctly.

I can confirm the bug and behavior reported by @aurelio1 and @eikowagenknecht.
