I tested on macos and Windows. The memory use never climbed. Not sure if the page is working correctly? Nothing seems to happen.

I'm going to resolve this as invalid given Timothy's testing.

We'd need a profile, the contents of about:support before this is actionable.

In order to scale up the memory, you need to zoom in, zoom out and move the map, seems that map keeps rendering and using more memory each render and neve clear that memory.

I don't see a map at all in the testcase, I just see a blank page.
