[MathML] MathMLOperatorElement::OperatorProperties::flags is read
uninitialized

flags had no initializer, unlike its sibling dirtyFlags, and m_properties is
not initialized in the constructor. computeOperatorFlag() then read-modify-
writes it (`flags |= flag` / `flags &= ~flag`), which is undefined behavior.
Zero-initialize it. No behavior change, no new test.
