To see how far this extends, I queried the HTTP archive.

Out of the 559 million “root pages” in the set, about 6k are affected by this – mainly in their usage of `cubic-bezier()`.

While this is very unfortunate, I believe the number of affected sites seems quite reasonable.

At worst the effects on those sites will run using a `linear` timing, instead of the custom one.

The fix is easy too: remove the whitespace.
