Change looks great but I am not sure I understand why the code was working.

> +        setProperty(AXPropertyName::MathLineThickness, object.mathLineThickness());

Wow, what was that?

> Source/WebCore/accessibility/isolatedtree/AXIsolatedTreeNode.cpp:195
> -        [&] (Optional<AXID> typedValue) {

This looks great.

I don’t understand why the old code even compiled, though! And if it did compile, why did it ever work. There’s no Optional<AXID> in the Variant.

Do we have test coverage for this?

no idea... some errant character slipped in at the last second

Definitely compiled and appeared to work (unless I screwed up badly).

Andres is working on setting up the test structure for this now.
