[MathML Core] Operator Dictionary: U+2202 ∂ Prefix should be (3, 0) not (2, 1)
https://bugs.webkit.org/show_bug.cgi?id=314486
rdar://176693587
Reviewed by Frédéric Wang Nélar.
This patch aligns WebKit with Gecko/ Firefox and Blink / Chromium.
Per the MathML Core operator dictionary [1], PARTIAL DIFFERENTIAL (U+2202)
as Prefix is lspace=3, rspace=0 (in 18ths of em). WebKit still ships the
MathML 3 values (2, 1), which is what op-dict-9-notref.html pins as the
"older MathML specification" rendering. As a result
op-dict-8.html fails (our spacing doesn't match MathML Core) and
op-dict-9.html fails (our spacing does match what the mismatch reftest
explicitly rejects).
