This signal is emitted when the user interacts with a <input
type='color' /> HTML element, requesting from WebKit to show
a dialog to select a color. To let the application know the details of
the color chooser, as well as to allow the client application to either
cancel the request or perform an actual color selection, the signal will
pass an instance of the #WebKitColorChooserRequest in the @request
argument.
It is possible to handle this request asynchronously by increasing the
reference count of the request.
The default signal handler will asynchronously run a regular
#GtkColorChooser for the user to interact with.
