🐛 Extension does not update Line Separators (and it breaks import sorting)

[jgreuter]

IDE and version

WebStorm 2025.1.3

Extension version

1.7.2

Biome version

2.0.5

Operating system

• Windows
• macOS
• Linux

Description

When having the document line separators on CRLF and Sort import on save in the extension enabled, the extension outputs invalid code. It also does not change the line separators from CRLF to LF.

Steps to reproduce

1. Create a Typescript file with unsorted imports (see playground link)
2. Set your line separators to CRLF
3. Save your imports (sometimes multiple saves are required, sometimes it breaks it even more)

Input:

Output with CRLF

Expected behavior

It should produce valid code even when the file is CRLF. It should also change the line separators.

Does this issue occur when using the CLI directly?

No
