Issue:

VSCode with latest Volar (1.8.8) complains about values that are declared and never read if values are used inside template with v-else of v-else-if.

Reproduction:

  1. Clone this repo: https://github.com/KamilBeda/nuxt-vs-code-typescript-bug
  2. Install dependencies
  3. Open app.vue and look at the error at doSomething function

Temporary fix:

Reverting Volar to 1.8.7

Reverting to 1.8.7 does not solve this problem :(

For me it does but it intruduced Vue language server crashes so I reverted to 1.8.6 and everything seems to work fine now

Interesting, when volar parses the code, the AST node of the second slot is totally lost!
