[Bug Report][3.6.4] Default prop values with a null value are ignored

[donalmurtagh]

Environment

Vuetify Version: 3.6.4
Vue Version: 3.4.27
Browsers: Chrome 124.0.0.0
OS: Mac OS 10.15.7

Steps to reproduce

Remove the mobile="null" prop value from the data table and wait for the demo to reload

Expected Behavior

The table should stay in mobile mode, because mobile="null" is the default value for this prop in vuetify.js

Actual Behavior

The table switches to desktop mode (presumably) because default props with a value of null don't work

Comment

I tried setting the default value to undefined instead of null, but that also didn't work.
