Duplicate entries in xref

[dontcallmedom]

Using e.g. {{MessagePort/postMessage()}} is reported as ambiguous when used in ReSpec, despite this being a well-defined single definition.

I think because xref provides both an argument-full and an argument-less version of the method, it appears duplicated in search results, and thus raises an error when used in ReSpec.

xref should de-duplicate methods in that situation.

Relevant code that causes this issue:

respec-xref-route/scraper.ts

Lines 134 to 139 in 7acc2a4

	if (termData.type === 'method' && /\(.+\)/.test(term)) {
	// add another entry without the arguments
	const methodWithoutArgs = term.replace(/\(.+\)/, '()');
	if (!data[methodWithoutArgs]) data[methodWithoutArgs] = [];
	data[methodWithoutArgs].push(termData);
	}

xref should de-duplicate methods in that situation.

What should be the correct de-duplication behavior in case of {{MessagePort/postMessage()}}? We've postMessage(message, transfer), postMessage(message, options) converting into postMessage(). The present solution is to be explicit. Should we remove postMessage() and keep only explicit versions?
