A Bashful Button Worth 8 Million Dollars

6 years ago I reported a bug about 100vh being larger than the viewport height in Safari. It was "intentional" according to webkit/Safari team, and other browsers followed… 🤦‍♂️

Now Jason shows here how this "tiny little annoyance"[1] may have cost $8.1 million a year to one single brand.

Imagine the total for all sites of other brands… 💸💸💸

As Jason says:

There is no substitute for testing on real devices

And he knows this more than anyone else.
