Hello,

I can reproduce the issue. It seems to work natively so it's not an Edge upstream.

Thanks @jacekbogdanski!

More to this issue - after using a clipboard viewer, edge seems to copy a bunch of wacky (word-like) tags - and adding the pasteFilter: 'semantic-content' seemed to filter out most of that junk before being handed to the ACF - which then did its thing correctly. I note that its on by default for CH and FF, but not MS* - but specifically setting it seemed to fix my issue above.

This is upstream issue with Edge 17,
https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/18089287/

However workaround for this is quite simple and I will propose PR for that.
