REGRESSION

Steps to reproduce:
1. Go to https://codepen.io/gmltA/full/NWZMBPy

Expected result:
A `footer` element with green background and text 'data' is visible at the bottom of the screen.

Actual result:
A `footer` is not visible at all.

MacBook (Apple Silicon): Chrome, Firefox, Safari 17.4
Android: Chrome

Fails on:
Desktop: Safari 18, Safari TP (v201).

P.S. The CSS is a bit wierd because I was trying to imitate the exact properties order from my production environment.
