Multi-caret editing on virtual space with EOL glyphs enabled breaks

[Rekkonnect]

Steps

1. Run the demo project found in this repo (AvaloniaEdit.Demo)
2. Enable EOL glyph view
3. Begin multi-caret editing between lines that may be shorter than the position of the caret
4. Begin typing

Expected

Correct placement of the characters for all lines

Actual

On the lines that are shorter than the position of the caret, the text is inserted by one position to the left than the correct position.

Example

multi-caret.with.eol.marks.mp4

(This is not related to typing Greek characters as shown in the example)

In a version of AvalonEdit (not AvaloniaEdit) I Implemented true multi caret support. It came together pretty easily and i ultimately replaced this Rectangular Selection with multiple selections when dragging the box. Hoping someday that can see the light of open source
