Caret clips off right edge of TextEditor

[Bip901]

Typing or arrow-navigating to the end of a long overflowing line causes the caret to become invisible (clipped ~2-4px off the right viewport edge).

The BringCaretToView() call (which is also presumably triggered by typing/arrow keys) undershoots at the document end, requiring manually dragging the horizontal scrollbar with the mouse to reveal the caret. This seems like a slight miscalculation, e.g. not accounting for the caret width.

For comparison, the regular Avalonia TextBox never clips the caret - once the end of the line has been reached, the caret stays fixed at the right side of the screen, despite keeping to type.

Minimal reproduction example (try typing a long line in both textboxes to feel the difference):
