tile filter primitive issue

On win 64 Inkscape 0.92.0 r15299 getting some unexpected behave.

Made a custom filter
producing a 10 px / 10 px black square,
added a tile primitive and
an offset to the chain.

If the offset is set to moving the square off the area, it doesn't appear on the other edges where a tile grid defined by the filtered area would bring them.

It either produces a glitch or renders nothing at all.
Attached an example with the first -if on of the offsetting value is 0 and the other is not, same thing happens.
