False positive check. Annoying warning. @firebase/firestore: Firestore: Host has been set in both settings() and useEmulator(), emulator host will be used

Look at the arguments here:

firebase-js-sdk/packages/firestore/src/lite-api/database.ts

Lines 294 to 301 in e642fc7

	export function connectFirestoreEmulator(
	firestore: Firestore,
	host: string,
	port: number,
	options: {
	mockUserToken?: EmulatorMockTokenOptions | string;
	} = {}
	): void {

Now look at how you set host in settings:

firebase-js-sdk/packages/firestore/src/lite-api/database.ts

Lines 312 to 316 in e642fc7

	firestore._setSettings({
	...settings,
	host: `${host}:${port}`,
	ssl: false
	});

Now look at how you comparing host:port (from settings) with host :

firebase-js-sdk/packages/firestore/src/lite-api/database.ts

Lines 305 to 310 in e642fc7

	if (settings.host !== DEFAULT_HOST && settings.host !== host) {
	logWarn(
	'Host has been set in both settings() and useEmulator(), emulator host ' +
	'will be used'
	);
	}
