Steps to reproduce:

I added an addEventListener("keyup", ...) to an input text. And when i press the 'Alt' key, only the 'keydown' is fired, the 'keyup' is not.

Actual results:

The keyup event is not fired and shows the Top menu.
After i press again Alt only the "KeyUp" is fired, keydown not.

Expected results:

Disable the toggle from Top menu by Alt.

Summary: When pressing the Alt key, the KeyUp event is not triggered → When pressing the Alt key, the KeyUp event is not triggered and vice versa
Component: Untriaged → DOM: Events
Product: Firefox → Core

Is this by design (related to menu access keys) or a bug?

Flags: needinfo?(m_kato)

Showing the memubar is by design and conformed to same manner of Windows application.

But not firing keyup event is a regression of e10s.
