Keyboard Button Interaction Bug

[SimeonC]

I found an odd bug to do with the mdButton directive and keyboard interaction.

Example here: http://plnkr.co/edit/6QhhohD5fwYtIkb8GDT3?p=preview

Steps:

1. Click into input.
2. Tab to normal button.
3. Press Enter/Spacebar - count increments by 2!
4. Tab to md-button
5. Press Enter/Spacebar - count decrements by 2!
6. Comment out the angular-material.min.js script and the DI in the module definition.
7. Repeat steps 1 - 3 - count increments by 1!!!

That is weird! I actually think it might be related to ngAria, which ngMaterial pulls in as a dependency. There is a bug in ngClick where it fires both click and keypress on native buttons and probably anchors, causing the callback to be run more than once. That could definitely cause problems like this! angular/angular.js#10388

This is still dependent on angular/angular.js#10388.

@SimeonC the fix for ngAria has been merged to Angular.js master and should go out in the 1.4 release, so I'm going to close this issue. I forked your Plunker to use angular-aria version 1.3.5 (the last version without the bug), and it appears to work fine. So I'm pretty sure the 1.4 release will solve your issue. http://plnkr.co/edit/x5T3fM6xj0JWlKXYPhdv?p=preview
