It works

PS: please don't open issues with incomplete reproductions, it's not showcasing what you say.

Thanks for the quick reply! I appreciate your patience on this, it is my very first time ever contributing to any open source project.

I did try this in that playground and could not recreate it, even with the versions matching the project:

• TS: 5.5.4
• Vue: 3.4.36
• Vue Router:
  • 4.4.0 (without issue)
  • 4.4.1 (introduces issue)
  • •••
  • 4.4.3 (still has issue)

My next thought was that it was an issue with vue-language-tools, but that did not give me any clues.

Finally, I decided to play around with the extensions and stumbled across something, so I've opened a PR which includes a demonstration of the issue as well as the partial reversion we could do to address it.

Thanks for all your hard work, @posva!

Thanks but the reproduction is crucial to move this forward

Makes sense, I'll try again!

I assume you were able to get a reproduction for the change that would be partially reverted since that change was accepted, right? I couldn't find that sandbox, all I see are screenshots. Could you point me towards that sandbox or whatever it was that let you reproduce?
