Hide context-menu on Esc key

[metaleap]

Might be sensible to have this logic right inside w2ui, it's a longstanding standard behavior across OSes: hitting ESC closes any open menu.

Right now, I have this helper in my app:

mySideBar.on('keydown', (evt) => {
    if (evt?.detail?.originalEvent?.keyCode == 27)
        w2tooltip.hide() // nevermind tooltips, it's really for closing the open context menu, if any
})
