Emmet completions not working correctly with multiple cursors

I’ve noticed today when I have multiple cursors active, emmet completions behave strangely. It’ll only detect the first character, so unless you wanted to bold a string, you can’t do much else. Typing a longer tag produces no suggestions and pressing tab does not work. If I try and use the command palette or keyboard shortcut to run the completion, it only works on the first instance.

Is this a Nova issue or an issue with the Emmet addon?
