click.delegate firing for all clicks on firefox rather than just left click about binding HOT 5 OPEN

@AaronJY thanks for filing this bug. It's interesting that FF behaves differently. I'm not sure how we should fix it, adding a check just for quirky browsers or doing something else?

No worries. I think a quick check on the value of event.which from the click event would be adequate enough on the surface, though I'm not sure if there's something crazier going on that is impacting FF specifically that needs to be addressed 🤔 If anybody with more experience with the code could shed some light before I start digging that would be ideal - happy to take a look myself though!

It's worth mentioning that I've tested the behavior on the latest version of Aurelia as well, so we're sure it's not been fixed in a later version! Here's a sandbox with an example: https://codesandbox.io/s/001jo2ql7l

Only left-clicking the Trigger link will update the textbox, however any clicks on the Delegate link will update it.

Interesting. It's funny we hadn't hit this before now. I wonder if it was a change in FF or if nobody just really cared which mouse button triggered it before. We could definitely add a check on which of click events. @bigopon What do you think? (We'd also need to port this over to vNext if we do that.)
