Screenshot of incorrect webkit rendering

Hello,

There continues to be a rendering bug when `height: min-content`, `position: absolute`, and `box-sizing: border-box` are combined in Safari, and any padding or border is also present on the element. I believe this was supposed to be resolved by https://bugs.webkit.org/show_bug.cgi?id=219944.

The rendering bug is clearly visible in this sandbox, where the height of the element is larger than its contents when a 2px border is added to the element: https://codesandbox.io/s/safari-min-content-19ccb?file=/src/App.js

This is present in version Version 15.1 (17612.2.9.1.20), as well as Safari Technical Preview: Release 134 (Safari 15.4, WebKit 17613.1.6.1). It is not present in other browsers.

Please let me know if any additional info is required!

Best,
Adam
