An ogc api request with a bbox (e.g. /ogcapi/collections/testlayer/items?f=json&bbox=2678483.5005230373,1286876.7365089145,2680778.0675097415,1287676.7148341944&bbox-crs=http://www.opengis.net/def/crs/EPSG/0/2056) returns too many features if a tolerance is set on layer level. The internal bbox seems to be influenced by the set tolerance.

A WFS Get Feature request with the same bbox returns always the correct features even if a tolerance is set.

Example layer snippet with tolerance

LAYER
  NAME "testlayer"
  STATUS on
  TYPE polygon
  TOLERANCE 1.0
  CLASS
    ...
  END
  METADATA
