Low precision interation with L.vectorGrid.protobuf

I am using L.vectorGrid.protobuf with rendererFactory: L.canvas.tile to show some vectortiles generated with tippecanoe.

Everything looks nice and fast, but the interactive:true option lacks some precision for some polygons.

You can see this happening on this gif:
http://sigserver3.udg.edu/map-vectortiles/low-precision-interaction.gif

all polygons are drawn (even small ones) but some of them are not detected when onclick event occurs, so and adjacent polygon is selected instead.

Also, you can try it by yourself here:
http://sigserver3.udg.edu/map-vectortiles

Any idea why this is happening? And better yet, how to solve it?

I have also tryed the SVG renderer with no problems, but there are too many polygons and everything goes very slow. My only option is to use CANVAS rendererFactory.

Thanks.

Start by reproducing the interaction issue in L.vectorGrid.protobuf with rendererFactory: L.canvas.tile and interactive:true using the linked map example. Compare polygon hit detection with the SVG renderer and inspect the canvas interaction path. Done means small polygons consistently select themselves without making the canvas renderer unacceptably slow.
