#4556: st_asmvtgeom sometimes produces leaking polygons (postgis 3.0)

 Priority:  medium   |  Milestone:  PostGIS 3.0.0
Component:  postgis  |    Version:
 Keywords:           |
---------------------+---------------------------
 st_AsMVTgeom in postgis 3.0 built with wagyu 0.43 sometimes produces
 leaking polygons.

 if a polygon is the surface of a circular road, the output polygon of
 st_asmvtgeom sometimes changes to a filled circle at lower (zoomed-out)
 zoom levels.

 I am attaching an example. Unfortunately I did not yet succeed to reduce
 the problem to a small data example.
