Pressing End to go to the end of the line ignores multi-character trailing whitespace

[Rekkonnect]

Steps

1. Run the demo project found in this repo (AvaloniaEdit.Demo)
2. Type multiple spaces at the end of any line
3. Make sure "View spaces" is disabled
4. Press Home and End

Expected

The caret is placed at the end of the line, right next to the last whitespace character.

Actual

The caret does not go to the final whitespace character, it only surpasses the first one.

Example

go.to.end.with.multi.trailing.whitespace.mp4

This works as expected when spaces are visible.
