Tiny nitpick: There’s not enough const here. This declares a constant string, and a non-constant global variable that starts out pointing to it; but we don’t need to change the value of that global variable. We should add another const or constexpr so the pointer itself is constant too, not just the string contents. Or could use a constant array instead of a pointer to a string; I think that is a little smaller.

Landed a follow-up fix in <https://trac.webkit.org/changeset/250916> thanks.
I opted for "static const char simpleUserAgentStyleSheet[]".
