The center text alignment is lost when the last paragraph is copied and pasted. 

Steps to reproduce:

- Enter some text and center it.

- Copy and paste it into another document.

Actual: the aligmennt is lost

Expected: the alignment should be preserved

To reproduce set he following properties: 

MouseSelectionHandler.DoubleClickTime = 1000;
MouseSelectionHandler.MouseDragThreshold = 2;

MouseSelectionHandler.MouseDoubleClickThreshold = 60;

Profiling results show bottleneck in the line-breaking logic within Paragraph MeasureOverride.

The TableCellProperty.Padding property of the "TableNormal" StyleDefinition doesn't take effect in the UI. The same is valid for the TableProperties.CellPadding property.

To work this around, you can manually set the Padding property of all TableCell elements in the RadDocument.

 var cells = radDocument.EnumerateChildrenOfType<Telerik.Windows.Documents.Model.TableCell>();
 foreach (var cell in cells)
 {
     cell.Padding = new Padding(10);
 }

The image adorner in is not shown in NetCore/6/7/8 when ApplicationTheme is not set (XAML only).

Workaround:

Explicitly set the theme:

 StyleManager.ApplicationTheme = new Office2016Theme();
