Log Message:
-----------
U+2016 (DOUBLE VERTICAL LINE) is missing the symmetric property in the
operator dictionary
https://bugs.webkit.org/show_bug.cgi?id=317070
rdar://179558196
Reviewed by Frédéric Wang Nélar.
The operator dictionary entries for U+2016 ‖ DOUBLE VERTICAL LINE (prefix and
postfix forms) were missing the symmetric property. Per the MathML Core
operator dictionary [1], both forms are { stretchy, symmetric } (categories F
and G). WebKit only had { Fence, Stretchy }, so a stretchy ‖ was not stretched
symmetrically about the math axis.
Add the Symmetric flag to both entries. Verified against the WPT operator
dictionary data (operator-dictionary.json) that U+2016 is the only character
whose symmetric property was missing.
