New pull request with one commit.

Humm, this is the opposite of what have been done in #3682.
This will break Leaflet.Editable. I'll try to have a look with a bit of calm to make a counter-proposal OR fix on Leaflet.Editable side.

Damn. Maybe make stopPropagation optional, and enable it just for the map container?

[turban]

Would it be possible to expose the original event so it can be stopped outside the API.

[yohanboniface]

@turban, you should have it in e.originalEvent

[turban]

@yohanboniface, I've not yet succeeded in doing that. Which event on the map should I listen to, to access the original event?

[yohanboniface]

I'd say something like:

map.on('mousedown', function (e) {
    e.originalEvent.stopPropagation();
});

See http://playground-leaflet.rhcloud.com/keri/edit?html,console,output for a playground ;)

I was sure I tested that @yohanboniface, but on a second try this seems to work. I'm happy to withdraw my pull request @mourner.

[mourner]

Reverted.
