// QgsIdentifyResultsWebView size:
// ---------------

// 1) QTreeWidget is not able to scroll continuously through the content of large widgets
// inserted into items via setItemWidget, it always jumps to the top of next
// item and it is not able to scroll to the bottom of an inserted large
// widget (until the QTreeWidget itself is large enough to show the whole
// inserted widget). => We have to keep the height of QgsIdentifyResultsWebView smaller
// than the height of QTreeWidget so that a user can see it entire, even if
// this height is smaller than QgsIdentifyResultsWebView content (i.e. QgsIdentifyResultsWebView scrollbar
// is added). We make it even a bit smaller so that a user can see a bit of
// context (items above/below) when scrolling which is more pleasant.
//
// 2) contentsSize() is 0,0 until a page is loaded. If there are no external
