Setting page fill property on WebView with no URL or content loaded has no effect.
To reproduce: run the attached SCCE, click on [TogglePageFill] button.
Expected: WebView acquires background color.
Observed: no change in background/page fill until an html content is loaded.
If the [LoadHTML] button is pressed before toggling the fill color, all is well.
One possible workaround might be setting some empty content like `<html></html>` right after instantiation of the WebView. This may or may not produce the desired result depending on how quickly WebView gets initialized, so there might be a visible delay and flicker.
Another workaround might be to place a Pane with the desired background underneath the WebView.
