vue-jest: Source maps for vue2 SFCs using TS are not created/wrongly created for v28

After upgrading to Jest v28 SFCs that are using TypeScript and the Composition-API plugin for Vue2 are producing a weird error:

FAIL  ***/FormDateInput.spec.ts
  ● Test suite failed to run

    No element indexed by 61

      4 | import Vue from 'vue';

    > 6 | import FormDateInput from './FormDateInput.vue';

It seems to me, that vue2-jest cannot produce source-maps or creates them i a way that is not consumable by the underlying source-map lib.

Relevant packages installed in a node 16 environment with npm 8 are:

• “@vue/vue2-jest”: “^28.0.0”
• “jest”: “^28.1.0”
• “ts-jest”: “^28.0.2”
• “typescript”: “^4.6.3”

I know that these version do not match exactly, but it makes no difference: Even if i downgrade all to exactly v28.0.0 it does not work

The transformers property lists @vue/vue2-jest correctly for transforming vue files, which also worked for vue-jest v27 and jest 27. I have also tried to include the full path in node modules like <rootDir>/node_modules/@vue/vue2-jest, but without success.

  transform: {
    '.*\\.(vue)$': '@vue/vue2-jest',
    '.*\\.(js)$': 'babel-jest',
    '.*\\.(ts)$': 'ts-jest',
  },

Unfortunatly i cannot include a repo link since its proprietary software.

Am i missing something in the way to upgrade to jest v28 or is this a bug?
