CORS errors loading any sample

[1ec5]

Selecting any sample results in a blank map and a slew of CORSRequestNotHttp errors about bogus request URLs such as openmapsamples-highway-attributes://landuse and openmapsamples-highway-attributes://park. The culprit appears to be this source definition:

OpenMapSamples-MapLibre/OpenMapSamplesControl.js

Lines 331 to 334 in d0bb7b8

	style.sources[sampleSourceId] = {
	type: 'geojson',
	data: `openmapsamples-${sample.getId()}://${sourceLayerId}`,
	};

This comes immediately after adding a protocol for “openmapsamples-highway-attributes”. Does the client application need to set up a CORS rule for every custom MapLibre protocol generated by a sample?

Reproduces in Firefox 143.
