[Bug Report][3.6.9] v-stepper-vertical: Data Loss on Step Change

[vciloglu]

Environment

Vuetify Version: 3.6.9 Vue Version: 3.4.29 Browsers: Chrome 125.0.0.0 OS: Windows 10

Steps to reproduce

In the v-stepper-vertical component, data filled and displayed via a button within a v-stepper-vertical-item is lost when navigating away to a different step and then returning. This issue negatively impacts user experience by causing loss of form data. Resolving this problem would ensure a more consistent and reliable user experience.

Expected Behavior

The data entered and displayed within a v-stepper-vertical-item should persist when navigating between different steps. Users should be able to move back and forth between steps without losing any previously entered data, ensuring a seamless and uninterrupted workflow.

Actual Behavior

Currently, data entered and displayed within a v-stepper-vertical-item is lost when navigating away to a different step and then returning. This causes users to lose their input and disrupts the workflow, requiring them to re-enter data.

You can set eager on each item, it should be inherited from the parent though.
