@keydown.escape does not work in Edge

[salomvary]

Version

2.5.16

Reproduction link

https://codepen.io/anon/pen/EEmBGm

Steps to reproduce

• Open the linked reproduction link in Microsoft Edge
• Open F12 developer tools console section
• Click inside the input field on the Codepen output
• Hit escape on the keyboard

What is expected?

@keydown.escape and @keydown.esc handlers should be triggered (should log 'esc' and 'escape').

What is actually happening?

@keydown.escape and @keydown.esc handlers are not triggered. Only the unfiltered @keydown handler and @keydown.27 are triggered.

Issue tested in Microsoft Edge 41.16299.15.0. Verified to be working as expected on latest Safari, Chrome and Firefox on macOS.

Cannot test on Edge right now but this may be related to the name Edge is giving to the name. If it's actually failing this is a good first issue, the fix should be at https://github.com/vuejs/vue/blob/dev/src/compiler/codegen/events.js#L21 (I can be wrong about the fix, but if I'm not it will help someone to get a contribution 🙂 )
