Define the order between select and selectionchange

[saschanaz]

There is no defined order between them.

• Mouse drag: selectionchange first and then select.
• Shift+arrow keys on keyboard: select first and then selectionchange.
• Selection setter APIs e.g. selectionStart: select first on Gecko, no consistency on Blink (it's racy).

The mouse drag case fires multiple selectionchanges and then a select event at mouseup. I think selectionchange events should be fired before select events to keep it that way.

I guess we should define both in the same specification as well? Probably HTML?

Am I correct to assume touch devices would also need to be considered here? I'm unfamiliar with the selection API in relation, but I understand the touchstart and touchend events sandwich the selectionchange event.

Yeah, that would make sense.
