The map on web is always on top of Compose UI

This means that dialogs, sheets, material3 controls, composable annotations, etc can't be rendered over the map.

Related: #184

Compose UI doesn't have support for HTML interop at all, so we have our own library: https://github.com/sargunv/maplibre-compose/tree/main/lib/compose-html-interop.

I'm not too familiar with the capabilities of the browser, but would it be possible to apply an alpha mask to either the Compose canvas or the MapLibre canvas to composite with each other?

#215 will fix this if we can figure out pointer interop
