Regression: Clicking too low on the trigger autoselects the first item in the dropdown list

[johanrd]

1. Go to the current docs for multiselect on v3/v4 and click on the bottom border of the input trigger.
2. Experience that the first item in the list is selected after a very brief flash of the list:

The same does not happen on the docs for v2 of multiselect, so this seems like a regression.

For debugging, I ran a test with adding margin-top: 1px to .ember-power-select-dropdown, and that made the problem go away. Therefore I suspect this to be an overly triggerhappy mouseup event.

mouse-control-test.js seems to be the guardian for cases like this, however it looks like this has managed to sneek through.

This is occurring in my team's application as well, but the margin-top workaround doesn't seem to work. Are there any updates on resolving this within EPS?

Edit: Quick update. The proposed fix seems to work with the default styles, but not with the included material ones.
