i-click fails with html entity present...

Seems like this is an aggressive regex type deal, but having an html entity inlined inside a button causes an acceptance test fail. Doesn't seem to matter what the entity is. It seems a blank space is needed to cause the entity to be ignored.

// $i->click('sign-in');

// this fails...
<button type="submit">
    <span class="fa fa-user"></span>&nbsp;sign-in
</button>

// this fails, variations...
    &nbsp;<span class="fa fa-user"></span>sign-in
    <span class="fa fa-user">&nbsp;</span>sign-in

//...and this doesn't...        
    <span class="fa fa-user"></span>sign-in
    <span class="fa fa-user"></span>&nbsp; sign-in
    &nbsp; <span class="fa fa-user"></span>sign-in

No biggie, but was a bit of a surprise trying to figure out why the test failed.
