By default, in Scala 2 completion prepend and only replace if there is exact match. This PR unifies the experience between the Scala versions. It seems more intuitive to work that way. The change will be as follows (the order is: new logic, old logic and scala 2 logic): https://github.com/lampepfl/dotty/assets/48657087/c037c322-5613-4b95-a6e5-090b4e8827b6 In the future, it should be improved by changing implementation to use `InsertReplaceEdit` instead of `TextEdit`. This will allow users to decide which behaviour they prefer, but this has to be first implemented in metals to properly handle the new logic, but for now the key is to unify behaviours. https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#insertReplaceEdit [Cherry-picked dc1e35a]
