I have a Vector Tile Package which I'm about to update, and have discovered an issue with the way symbols for polygons with a boundary offset applied are drawn. As can be seen in the 3 examples below, at some scales, where the Index grid crosses features, the boundaries are being drawn as if the index gridlines are a part of the feature. The 1:50,000 image (the first one) shows the features (the pink lines) drawn correctly. The 2nd isn't.



You can see in the below screenshot, that this problem exists in FieldMaps too (though manifests a bit differently).
