Hello,
Is this by any chance related to thisissue we encountered in Webstorm?

Hi@qyzzzz, this looks like a very interesting change. This also looks like a very big change and unfortunately I'm away at the moment, but will try to look in a week or so when I'm back.

Can you confirm that you've tested that everything still works for users with other configurations than yours? It's unfortunately quite hard to test, you need to do it manually.

Hi@mrmckeb, sorry for delay here.
I have determined the feasibility of this solution by reviewing and comparing the unit test snapshots in your project.
Additionally, I have created a separate project for manual effect testing. In this round of modifications, I primarily examined the impact of these changes on the goToDefinition, namedExports, and allowUnknownClassnames options.

Unfortunately, I am currently using VSCode and have not tested with Webstorm.😅
