@skyclouds2001 FYI

[skyclouds2001]

per BCD, this feature is not standard and only supported in chromium-based browsers

as for my test using https://worker-playground.glitch.me/ also indicate this feature is only available in window scope

also confirmed in chromium source code

I think you mean "only available on window"? The IDL in Chromium also says it's only exposed on window.
