Remarks

Known Issues

ContentDialog controls should be direct children of document.body. Otherwise, it is possible to mask event detection on the ContentDialog due to stacking context effects. This is because event detection for other elements is blocked while the ContentDialog is open. So, if the ContentDialog is a child of one of those blocked elements, it too will be blocked. This behavior is typical for all overlaying controls.
