    @discussion A WebView's WebFrameLoadDelegate tracks the loading progress of its frames.
    When a data source of a frame starts to load, the data source is considered "provisional".
    Once at least one byte is received, the data source is considered "committed". This is done
    so the contents of the frame will not be lost if the new data source fails to successfully load.
