Reviewed by Antoine Quint.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Inspired by: https://chromium-review.googlesource.com/c/chromium/src/+/2584970

The spec says the behavior is currently undefined [1] and implementations
should not apply the property to generated content. Although it is still part of
the computed styles.
