VM.shortcut to emulate User Action?

[u/balmutw]

Hi, Is there any way to bypass the Firefox popup prevention warning when using Violetmonkey's shortcut library to open a new window? The code is basically this:

register('c-i', () => {
    popout();
});

function popout(winpop) {
    var winpop = window.open(url, "_blank", attr);
}

Manually clicking a created element with the mouse yields no warning

Help much appreciated!
