How does the Wikidata script select a Facebook icon?

While looking at another issue, I noticed that McDonalds is using the South Africa Facebook Logo, which currently doesn't show a meaningful McD's logo.

This isn't an issue as such, as dist_files.js already overrules Facebook to use a Commons Logo, but it did make me wonder why the South African Facebook logo is being chosen by the Wikidata script over the main McDs Facebook, when the main one has a preferred rank.

Is it because the South Africa one is the last in the list, does the Wikidata script not factor in rank?

The script does prefer any statement with preferred rank, so I’m unsure why that isn’t working:

name-suggestion-index/scripts/build_wikidata.js

Line 507 in 1a86c90

// - accept immediately any claim with "preferred" rank

name-suggestion-index/scripts/build_wikidata.js

Lines 334 to 335 in 1a86c90

	// P2013 - Facebook ID
	const facebookUser = getClaimValue(entity, 'P2013');

It’s only showing up now because someone recently dumped a ton of regional statements onto the global McDonald’s item, even though each regional subsidiary already has its own item, including McDonald’s South Africa (Q27923821). I’m tempted to simply revert the changes, but probably the better option would be to move the statements to the appropriate items.
