Firefox mouseleave@document action does not work

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.

Start by reproducing the data-action="mouseleave@document->newsletter-popup#show" example in Firefox and compare it with the working Chrome behavior. Trace how Stimulus attaches document-level actions, then determine whether the issue can be fixed in the event handling or needs a documented limitation and workaround.
