FYI this is not really an issue with vscode-haskell - it more closely related to haskell-language-server, which contains hlint plugin, which in turn uses apply-refact library to apply automatic fixes to some hlint warnings. The issue has been reported in apply-refact repo some time ago: https://github.com/mpickering/apply-refact/issues/140
Hi, thank you for bug report!
I think the same issue is reported at https://github.com/haskell/haskell-language-server/issues/4143
No worries!
I am closing this as a duplicate of https://github.com/haskell/haskell-language-server/issues/4143, though. Feel free to reopen or open other issues if you think we've missed something!
