描述

When I edit a polygon with a zoom level low and I snap this polygon to another one, it's very common the created snap point is not exactly on the line / point. For me, it's a problem regarding I control if these polygons are not intersecting.

研究方向
Investigate the snapping logic in the leaflet geoman source code, likely in files like src/js/Edit/Snapping.js or similar. The issue mentions low zoom levels affecting precision; check coordinate rounding or snapping threshold calculations. Review comments #715 for any hints from maintainers. Look at how snap points are computed and compare them to the geometry coordinates.
