hm this does work for me it seems the bracketed paste is losing the newlines somewhere

Can't reproduce anymore. I think bracketed paste wasn't implemented when I opened the issue.

Now Command+Shift+Paste is not working at all on dev branch. I think this issue needs to be reopened. Instead of pasting from the global clipboard, but only from the local terminal clipoard, so cannot paste from another app.
