//
// From StyleBuilder's point of view, there's a dependency cycle:
// letter-spacing accepts an arbitrary <length>, which must be resolved against a font, which must
// be selected after all the properties that affect font selection are processed, but letter-spacing
// itself affects font selection because it can disable font features. StyleBuilder has some (valid)
// ASSERT()s which would fire because of this cycle.
//
// There isn't *actually* a dependency cycle, though, as none of the font-relative units are
// actually sensitive to font features (luckily). The problem is that our StyleBuilder is only
// smart enough to consider fonts as one indivisible thing, rather than having the deeper
// understanding that different parts of fonts may or may not depend on each other.
//
// So, we update the font early here, so that if there is a font-relative unit inside the CSSValue,
// its font is updated and ready to go. In the worst case there might be a second call to
// updateFont() later, but that isn't bad for perf because 1. It only happens twice if there is
// actually a font-relative unit passed to letter-spacing, and 2. updateFont() internally has logic
// to only do work if the font is actually dirty.
