Markdown editor renders three line-ending arrows for CRLF files

Type: Bug

1. create a markdown file with encoding set to CR/LF

# one

## two

### three

The Markdown Editor shows **three** carriage return symbols (↵) for blocks one and two.

When text file encoding is set to LF - the correct number of symbols is shown.
