In the other project we shown a normal label on top of the input because polyfills doesn't work well with password inputs

It does work on IE in both auth0/lock and auth0/widget.

The thing is on IE, when focus is on input, placeholder wipes out.

I've also add some tests for this feature on IE and Chrome.

These are the results of IE:

For IE11 and 10

For IE9 fallbacks to a label above each input

Results for Chrome, Firefox and Safari are the same as IE11 and IE10 (on these cases)

Closing since it's actually working and already notified to kbennet about it.
