[Popover] Blinks on open in latest Safari (macOS and iOS)

Latest version

Current behavior 😯

Popover and components which use it (such as Select) flash when opened or closed. They seem to briefly appear to be fully open, and then begin their transition in (or out).

Expected behavior 🤔

Popovers and selects should open/close normally as they do in Chrome and Firefox.

Steps to reproduce 🕹

Steps:

1. Visit https://mui.com/components/popover/ or https://mui.com/components/selects/ or any website using the latest version of MUI components that has selects or popovers.
2. Open any select or popover and observe the behavior.

Context 🔦

This only seems to have become an issue with the very latest iOS update and Safari update.

Your environment 🌎

Safari v15.4 on macOS Monterey (v12.3) Safari on iOS v15.4

Happens also on components such as Menu where removing transition with transitionDuration=0 "fixes" it . Seems to be because of the Grow component as it doesn't happen on other transitions such as Fade or Slide, duplicate of #31849 ?
