            Bug ID: 282765
           Summary: REGRESSION(285102 at main):
                    AXIsolatedObject::{mathPrescripts, mathPostscripts}
                    always return nothing due to type mismatch, causing
                    accessibility/mac/mathml-multiscript.html to fail in
                    ITM
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

After https://commits.webkit.org/285102@main, we cache AXPropertyName::{MathPrescripts, MathPostscripts} as a Vector<std::pair<Markable<AXID>, Markable<AXID>>>, but the AXIsolatedObject::{mathPrescripts, mathPostscripts} getter functions were not changed to look for a Markable<AXID>, meaning they always find nothing.

vectorAttributeValue<std::pair<AXID, AXID>>(AXPropertyName::MathPrescripts)

vs.

vectorAttributeValue<std::pair<Markable<AXID>, Markable<AXID>>>(AXPropertyName::MathPrescripts)
