web-bluetooth connection dialog broken

[alterNERDtive]

I’ve been thinking about getting some Bluetooth dice, so I’ve been playing around with the Pixels dice integration.

I managed to enable web-bluetooth by passing --enable-experimental-web-platform-features --enable-web-bluetooth to the executable. But when this dialog (pic taken off Chromium)

should appear after hitting “Add Pixel Dice” in the settings, instead I immediately get

which, as it states, appears in Chromium when I actually cancel the thing. It appears that the Electron app either blocks the dialog from opening or somehow causes it to die instantly.
