What value is supposed to be stored in cache?

[DmitrySharabin]

For now, these lines (which, in my opinion, should be removed, and the corresponding returned value should be adjusted)

supports/src/types/html/element.js

Lines 22 to 25 in c8699e3

	cached[name] = {
	success,
	interface: interfaceName,
	};

cancel the one above

supports/src/types/html/element.js

Line 20 in c8699e3

cached[name] = success ? interfaceName : false;

We have leftovers of some sort, no?
