I guess (no verification done) that in the background the limit is
forwarded to the dataprovider which returns 3 features from which 1 is
filtered out by the layer so only 2 remain.

Please report this as a bug. I'm not sure if an action will be taken,
most of the "fixes" to this which I can think of defeat the purpose of
sending as few requests as possible to the database, but on the other
hand, this situation here can really lead to confusion.
