Description

Steps to reproduce

Steps:

  1. Open this link to live example: https://codesandbox.io/p/sandbox/transition-group-with-horizontal-collapse-2frjrp
  2. Click on the "Add" button several times
Current behavior

In some instances a strange twitching happens. This event stretches the page, hence why there is a scrollbar for a brief moment. The card has a full width for a split second, and then it goes back to 0 width and expands slowly.

Expected behavior

The animation is smooth. There is no twitching, it starts from 0 width and expands as expected.

Context

I'm trying to achieve this exact scenario from the documentation but in a horizontal manner.
