What version of ESLint are you using?

9.34.0

What version of eslint-plugin-vue and vue-eslint-parser are you using?

  • vue-eslint-parser@10.2.0
  • eslint-plugin-vue not used

What did you do?

If both <script setup> and <script> sections are present in SFC, some rules from at least typescript-eslint ESLint plugin start reporting less problems, but only in <script setup> section. <script> section shouldn't even contain anything for this problem to arise.

Some affected rules:

What did you expect to happen?

Other ESLint plugins receive correct information about SFC source code.

What actually happened?

They seemingly do not.

Run npx eslint and observe that many problems from <script setup> block are not reported (expected: 8, actual: 5).

Comment out <script> section, run npx eslint again and problems will be reported.
