Description Oriol Brufau 2022-09-30 15:10:11 PDT

StyleProperties::asTextInternal uses these 2 bitsets of size numCSSProperties.
But as the name implies, they are only used for shorthand properties, which since bug 238888 are sorted together.
So the bitset size could actually be lastShorthandProperty - firstShorthandProperty + 1.
The change would be from 505 to 88 according to https://searchfox.org/wubkat/source/__GENERATED__/WebCore/DerivedSources/CSSPropertyNames.h#525,536-537
