Setup

• oxfmt setting endOfLine: 'crlf'
• File content with LF, example debugger;\ndebugger;\n

Problem

When formatting the file will, oxfmt --lsp will generate internally debugger;\r\ndebugger;\r\n.
Then it calculates the minimal text edit.
The minimal text edit on this example is: \r\ndebugger;\r.
The result is returned to the editor.
The editor now sees the solo \r at the end, and will append a second line, next to the \n line.

Positions are line end character agnostic, so you cannot specify a position that denotes \r|\n or \n| where | represents the character offset.

Expected

The minimal text edit should be \r\ndebugger;\r\n, and covering the \n position too, so the editor knows that we want to replace the line, instead of appending one.
