Broken inline comments within explicit undefined bindings

[barthy-koeln]

Vue version

>=3.4.26 (worked fine until 3.4.25)

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-k1clft

Steps to reproduce

Have a property binding in a template that explicitly used the value undefined AND an inline comment:

<p :id="undefined /* force override the id */">This bugs out</p>

What is expected?

The value undefined is passed to the component or element.

What is actually happening?

The build fails with this error message:

error during build:
[vite:vue] Cannot read properties of null (reading 'type')
file: […]/src/components/TheComponent.vue
at […]/node_modules/@vue/compiler-dom/node_modules/@vue/compiler-core/dist/compiler-core.cjs.prod.js:4283:48
[…]

Or sometimes on Stackblitz:

[plugin:vite:vue] parent is null
/home/projects/vitejs-vite-k1clft/src/App.vue

System Info

No response

Any additional comments?

We use this to override specific properties passed using a v-bind. We pass undefined and add a comment why, as overriding something is mostly a workaround for a third-party-library.

<AComponent
  v-bind="CommonPropsObject"
  :specific-prop="undefined /* do not pass specificProp to avoid abc and xyz */"
/>

This is effectively equivalent to:

<AComponent
  v-bind="{
    ...CommonPropsObject,
    specificProp: undefined  /* do not pass specificProp to avoid abc and xyz */
  }"
/>
