* ManualTests/button-that-focuses-itself-on-click.html: Added.

Source/WebKit2:

This issue occurs when this site focuses the submit button. When it
receives focus, we try to assist it. While we consider ourselves to be
assisting it, we ignore further gesture inputs for that node, including
the tap gesture.

To fix this, only assist input types that we know are assistable,
including text fields, select and date elements, etc.

Reviewed by Darin Adler.

* UIProcess/ios/WKContentViewInteraction.mm:
(isAssistableInputType):
If the type is a known-assistable type, return true.
(-[WKContentView _startAssistingNode:userIsInteracting:blurPreviousNode:userObject:]):
Call isAssistableInputType() to determine whether we should do any kind
of assistance for this node.</pre>
