useBeforeUnload - not preventing unload

[chrisspiegl]

It looks like the e.preventDefault() is not enough in some browsers (Brave is where I tested).

However, if I also do e.returnValue = '', it does prevent and ask if I really want to close the tab.

This would be an easy fix:

const handleBeforeUnload = (e: BeforeUnloadEvent) => {
    // Show alert message only when isPageDirty is true
    if (isPageDirty.value) {
        e.preventDefault()
        e.returnValue = '';
    }
  }
