[Dão Gottwald [:dao]]

Gijs, thoughts on how to address this?

Comment 2

[:Gijs (out for now; he/him)]

I think we have a few options:

1. detect mousemoves/mouseovers as well, which is a little sad-making, perhaps, from a perf perspective
2. add fallback in onpopupshowing or oncontextmenu, which might cause a flash of unlocalized content, I guess?
3. move from mousedown to mouseup on windows (and/or linux? mac context menus appear onmousedown...) and/or use both
4. add some kind of complicated helper that intercepts an initial context menu showing, cancels it, and then re-opens it when l10n is ready

I'd be inclined to go for 2 or 3, but I'd like a second opinion. Jared, Dão, what do you think?

[Jared Wein [:jaws] (please needinfo? me)]

Can we add a capturing {once: true} mousedown event listener on the whole window and just initialize on that?

(In reply to Jared Wein [:jaws] (please needinfo? me) from comment #3)

Can we add a capturing {once: true} mousedown event listener on the whole window and just initialize on that?

Apparently I was confused and we already have a mouseover listener? I don't know off-hand why that wouldn't fire in the steps in comment #0...

The mouseover listener is only on the tabContainer. I assume holding down the right mousebutton while dragging it skips the mouseover event.
