Version

3.0.11

Reproduction link

https://codepen.io/bsalwiczek/pen/zYNeLGw

Steps to reproduce

Use v-model (in the component) referring to attribute of object indexed by the item in an array. Something like v-model="y[x[0]]" where y is object and x is array.

What is expected?

I'm expecting v-model to correctly interpret which item I want to refer to (using :model-value with @update:model-value works - check reproduction link).

What is actually happening?

The warning shows in console

and v-model don't work as expected.
