Copying & pasting a table from Atlassian's Confluence causes table's content to be stripped away.
This is because TextIterator is skipping the rendered text because it think it’s fully clipped due to a div that contains table in the markup below. This is in turn due to createPageForSanitizingWebContent creating a 0px by 0px FrameView.
