Set the default download dialog margin relative to the WebView corner
specified by DefaultDownloadDialogCornerAlignment. The margin is a
point that describes the vertical and horizontal distances between the
chosen WebView corner and the default download dialog corner nearest to
it. Positive values move the dialog towards the center of the WebView from
the chosen WebView corner, and negative values move the dialog away from
it. Use (0, 0) to align the dialog to the WebView corner with no margin.
The corner alignment and margin should be set during initialization to
ensure that they are correctly applied when the layout is first computed,
otherwise they will not take effect until the next time the WebView
position or size is updated.
