[Feature Request] Request to improve the color transition when switching the variant property of the VInput component from solo-filled to solo

[ahas]

Problem to solve

Example

In the example, when switching the variant property from solo-filled to solo, a black flickering issue occurs. This issue was not present in Vuetify 2.

Proposed solution

Vuetify 2 Implementation
I hope the black flickering issue can be resolved so that it behaves like it did in Vuetify 2, without any flickering.
