fix(VAutocomplete/VCombobox): consistent open/close transition

[J-Sek]

Description

At the moment only VSelect has nice expand transition. I wish to make it a default for all selection components.

Markup:

<template>
  <v-app theme="dark">
    <v-container max-width="600">
      <v-card>
        <v-container fluid>
          <v-select label="v-select" :items="shortList" />
          <v-combobox label="v-combobox" :items="shortList" />
          <v-autocomplete label="v-autocomplete" :items="shortList" />
        </v-container>
      </v-card>
    </v-container>
  </v-app>
</template>

<script setup>
  const shortList = [0, 1, 2, 3, 4, 5, 6]
</script>

• You could just omit the override, that's already the default for VMenu.
• This was here because combobox and autocomplete clear the filter when the menu closes which causes the full list to appear for a moment if there is a transition.

I see.. maybe useDelay would help here.

Edit: Upon inspecting the cause of this glitch, isPristine was reset to true in the inconsistent manner and since it is usually called in onAfterLeave, it should be fine without a few early calls. Now a few of the browser tests are failing, but I cannot imagine anything is broken just because of transition change.

This has the opposite problem:

Arguably it is still a progress, but let me take another look.
