On: Cannot read clipboard from service worker in a MV3...

[fosefx]

I came across this because I wanted to port an addon over to MV3. It simply used navigator.clipboard.writeText(). That by itself only works as a reaction to a user interaction (so not in bg scripts), unless you declare the "writeClipboard" permission in the manifest.

I don't know if there is a readClipboard permission as well.
