SyntaxEditor.Caret gives wrong value for out of bounds line/column

For an editor containing only 5 lines of text, when I set SyntaxEditor.Caret to Line 10, the displayed caret is displayed as the last position in the editor  (last column in Line 5 - which is expected). However SyntaxEditor.Caret.Position.Line is still line 10.

I would expect SyntaxEditor.Caret.Position and CharacterColumn/DisplayCharacterColumn to reflect the displayed position and not the set position.
