Firefox mouseleave@document action does not work

[papppeter]

My problem is that mouseleave@document at firefox does not work, there are some workaround which could make it work, but i cannot implement it inside stimulus.

This shows clearly the issue
https://stackoverflow.com/questions/66245558/mouseenter-and-mouseleave-event-listeners-on-document-not-working-in-firefox

document.addEventListener("mouseenter", () => {
console.log("mouseenter");
});

does not work on firefox
document.querySelector("body").addEventListener("mouseenter", () => {
console.log("mouseenter");
});
or
document.documentElement.addEventListener('mouseleave', () => {})
does work.

any hint how i could make it work?

thanks for suggestions

my action data looks like following:
data-action="mouseleave@document->newsletter-popup#show"
which works perfeclty under chrome.

Firefox version is: 113.0.2

Have you tried mouseout, as mouseleave does not bubble.

Hence Firefox may be more correct here, as your cursor is unlikely to leave the body or document element.

But mouseout will trigger when any descendant elements have a mouse move out of them.

Also, this is not really a Stimulus problem as Stimulus actions are just a shortcut to attaching event listeners.
