Fix edge-to-edge behaviour for landscape WebView alerts

by side-stepping the broken landscape `fitsSystemWindows`
(see a148480)
by changing the alert to be floating rather than fullscreen.
The non-fullscreen alert isn't particularly wide,
but if you're viewing the About or Help in landscape,
you deserve to be punished.
