User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116 Safari/537.36

Steps to reproduce:

Counted key presses for key combinations
https://github.com/watir/watirspec/blob/master/element_spec.rb#L309

This is the input field:
<input id="receiver" onkeydown="log(this)" type="text">

I'm sending cmd+a and it shows up as 3 onkeydown commands

I think it might be because we are appending a null key to the array getting sent?
(the code execution is the same as this one: https://gist.github.com/titusfortner/6f5ef27c96c90a15f57e)



Actual results:

3 key presses recorded


Expected results:

2 key presses recorded

I created a unit test for marionette that shows this issue (See attachements www/keydownPage.html and tests/unit/test_keydownbug.py).

When pressing Alt+Meta+n it outputs "keydown 224 keyup 224 keydown 18 keyup 18 keydown 78 keyup 78" instead of "keydown 18 keydown 224 keydown 78 keyup 224 keyup 18".

Is this still the case?

Yes, I can confirm this is still the case in Firefox 60

This bug has nothing to do with actions but with SendKeysToElement. We would have to check if using the Actions API fixes it. If yes then it would be fixed by bug 1418995. Marking it as dependency for now.
