Azure Map Rendering issues

We have an issue with maps rendering on certain zoom levels.

As an example here when we are zooming on the map near to "street level" the polygon does not render correctly.78decc3b-ab3e-4b29-bd08-359facc99b5d

Zooming out fixes the issue.

We are using a PolygonLayer with HtmlMarkers for these dots.

Is there a way to fix this issue by using a different kind of polygon rendering? We see that zooming out does show the polygon correctly but the issue seems related to a specific zoom level.

    It looks like there is a straight line point down there, like the seam between vector tiles. With this in mind, I suspect the root cause of the issue is that your polygon isn't closed. Valid polygons have the same start and end point. So, your polygon should have 5 points where 0 and 4 indexed points are the same.
