The map on desktop is always on top of Compose UI

[sargunv]

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

There's an upstream issue to support SwingPanel interop blending by default: https://youtrack.jetbrains.com/issue/CMP-4941/Make-SwingPanel-interop-blending-by-default

I tried enabling it manually with:

System.setProperty("compose.interop.blending", "true")

but the app crashes on launch with that enabled. Unsure if it's an issue with the property in general or specific to the webview implementation we're using. But even with that resolved, there's caveats described in the upstream issue.
