Errors are highlighted in wrong parts of lines indented with tab.

Your environment

Which OS do you use: Windows

Steps to reproduce

Cause an error in a line indented with tab:

Expected behaviour

The problematic part of the line is highlighted.

Actual behaviour

The highlight starts 7 characters too far to the right, so I guess the tab character is counted as one character when the highlight position is calculated, whereas HLS seems to expand it to 8 characters. This also affects type info popups, etc.

Include debug information

Range: 259:21-259:32
Source: typecheck
Severity: DsError
Message: Variable not in scope: nonExisting

Hi, thank you for your bug report!

I can locally reproduce, and will move the issue to the main HLS repo.
GHC behaves correctly, btw.

Seems to be the same problem as in #1987
