Save initial value before focus

[ktj]

Saving node initial value to variable before focus, so components that clear input on focus work

[ktj]

Any input? @vitalyq

Thank you for bringing up the issue. There are some problems with this approach. Ideally, we should get rid of this focus event altogether. I was thinking about monkey patching nodeName on the element or even document.documentMode but further testing is needed.

As a quick fix, please restore the value explicitly or make a wrapper function.
