Description
I tried it with QGIS 2.18.4-1 as well as 2.99.0-32 (nightly build), both with the same behaviour. I wanted to add a WFS point layer. The WFS I use is https://geodienste.ch/db/av , I added for example the layer 'Einzelobjekte (Punkte)'. That works fine so far.
Now I want to add a filter on this specific layer. The query I placed in the query builder is "Kanton" = 'BE'. The feature count is now reduzed, but the all the features displayed in the map disappear.
I also tried to make the query adding the WFS layer (see printscreen). The layer is added, but no feature is displayed in the map.

Ater investigation, this is an issue with the WFS server itself, where spatial + attribute filter fail (I tried all 3 WFS version=
For example

The workaround here is to disable "Only request features overlapping the view extent", but the issue is on the server
