bug(vue-model): does not pass values when using an object string

Vue version

3.4.28+

Steps to reproduce

Ionic Framework has a ion-range that can be set for dual knobs by passing a string object to the value.

1. Make sure to use Vue 3.4.28+
2. Navigate to the repro to see the dual knobs of ion-range.
3. Notice that the first knob has a value of 20 and the second knob has a value of 80.
4. The knobs render as a value of 0

What is expected?

I expect that the knobs render at the correct values. The correct render can be viewed at this additional repro that has Vue 3.4.27.

What is actually happening?

It seems that Vue 3.4.28+ is not passing the string object. It converts it to a NaN instead which leads to the knobs rendering at the 0 position. This is happening when ion-range is using dual knobs. However, no issues are found when downgrading to Vue 3.4.27.

Any additional comments?

We noticed this bug after a CI check failed. There hasn't been any changes to the ion-range since last month. The only thing that has changed was a patch release from Vue.
