WebContentsAdapter is not created together with the QQuickWebEngineView.
Thus querying a view property can lead to a crash if it uses the adapter.
This fix adds the missing guards for contentSize and scrollPosition
as it is done for similar WebEngineView properties.

The docs were wrong in that the default is actually text/plain with
US-ASCII encoding (see e.g. data_url_unittest.cc).

Anyhow, saying it might change in the future does not help anyone,
and is actually a potential security risk - see e.g. the discussion
about 'magic' in QTextEdit::setText(). Because of this, it's
unlikely that Chromium ever changes the default. Anyhow, we can as
well hardcode the default, and document it then.

was possible to run out of memory because the images that pdfium has
generated was cached for reuse when printing multiple copies of the

Caching the images is now removed as printing multiple copies is not
the default use case and is nowadays often also handled by the printer
