I recently had to exemplify a list of e-mail addresses which I did by double quoting the original address and append @example.com
.
For example
foo@bar.baz
I converted to
"foo@bar.baz"@example.com
To my big surprise I found that the resulting e-mail address validates as invalid in the HTML5 input=email field validation, i.e.
<input name='foo' type='email' required='required' />
Does this not make the build in HTML5 validation of e-mail addresses completely useless as it block potential valid e-mail addresses, or am I missing something here?
