... because trying to activate this view on load will throw and crash Unlike in Writer (SwPagePreview), Calc's ScPreviewShell overrides WriteUserDataSequence to export the view data. This was implemented in commit 1f51730f3c5b05c3afaa35431c925482e8152783. That does not give any clue why is this necessary, so I don't want to revert it. So to pass the flag to XViewDataSupplier::getViewData, this patch sets the flag in current context using comphelper::NewFlagContext. This allows to only skip providing the data conditionally.
