IE11 user login email validation fails if field has leading or trailing space

[dnadle]

Preconditions

1. Magento 2.1.0
2. IE11 browser
3. Chrome 51 browser

Steps to reproduce

1. Attempt login using IE with a valid user email but place a space either before or after the address.
2. Try again with Chrome.

Expected result

1. Client-side email validation should work the same in IE11 as it does in Chrome.

Actual result

1. Using IE, client-side validation fails with "Please enter a valid email address (Ex: johndoe@domain.com)."
2. Using Chrome, login succeeds. (padded whitespace is presumably trimmed?)

I received a report that Firefox behaves like IE11.
