Looks good.

For the benefit of anyone else reviewing this...

This is testing an if check in baseHandlers.ts:

core/packages/reactivity/src/baseHandlers.ts

Lines 226 to 228 in 94b9b37

	if (!isSymbol(key) || !builtInSymbols.has(key)) {
	track(target, TrackOpTypes.HAS, key)
	}

Currently, all the tests will pass even if that check is changed to if (true). The test added here catches that.
