Code Review
This pull request adds support for fallback font families in WebTextStyle and updates WebStrutStyle to apply styles using WebTextStyle. It also adds a test verifying fallback font rendering. Feedback on these changes highlights that unconditionally quoting the font family and bypassing canonicalizeFontFamily can break generic font families, and that fallback fonts themselves should be canonicalized. Additionally, the reviewer noted that fontFamilyFallback was omitted in WebStrutStyle's usage of WebTextStyle, and pointed out leftover commented-out code.

Should we skip the caller-provided fallbacks if the main font family is a generic or Apple font?

That's what we do already, unless I'm misunderstanding your question. This whole block of code is guarded by needsFallback which checks for exactly what you said.
