Other comments

e.stopPropagation() is called unconditionally on all click events triggered on menu component.

vuetify/packages/vuetify/src/components/VMenu/mixins/menu-generators.js

Lines 80 to 86 in 67b73b9

	on: {
	click: e => {
	e.stopPropagation()
	if (e.target.getAttribute('disabled')) return
	if (this.closeOnContentClick) this.isActive = false
	}
	}

It breaks scripts that use event delegation pattern: https://gomakethings.com/why-event-delegation-is-a-better-way-to-listen-for-events-in-vanilla-js/.
For example rails ujs uses it: https://github.com/rails/rails/tree/master/actionview/app/assets/javascripts

This was added in f154158 and moved in 5be0050, might be safe to remove now. There's also a conflicting feature request #3333.

Was originally added in #417 to fix a bug that is no longer relevant. It also doesn't conflict with the fix for #3333
