>+        Fixes an issue where it is not possible to submit a <form> with target = "_blank", that is,
>+        a form that opens a new window.
>+
>+        By default we only allow popups to open if they were user initiated (like a person clicked on
>+        a link). We achieve this by putting a token on the stack, called the UserGestureToken, when
>+        WebCore processes an event from WebKit. So long as this token is on the stack we consider
>+        all requests to open a popup to be user initiated. And we implicity submit a form when pressing
>+        the Return key in an HTML input element during the processing of a TextInputEvent dispatched as
>+        part of inserting a \n into the field. On Mac, the keydown dispatches a TextInputEvent synchronously.
>+        However on iOS text insertion, and hence a dispatch of a TextInputEvent, occurs asynchronously
>+        with respect to the keydown event. So, by the time the UI process calls back to the WebProcess
>+        to perform the text insertion of '\n' we have long since popped the UserGestureToken off the stack
>+        and hence we disallow opening a popup. To fix when -insertText is called we query the keyboard
>+        to determine if its being called by the keyboard. If it is then we can assume that this is
>+        part of key event handling and hence was initiated by the user. We can pass along this detail
>+        to the WebProcess for it to take out a push a new UserGestureToken onto the stack.
>+
>+        * Platform/spi/ios/UIKitSPI.h: Expose SPI.

>+        * WebProcess/WebPage/WebPage.cpp:
