Similar issues can be reproduced with:
---
Object.prototype.localeMatcher = "invalid"; 
Intl.NumberFormat.prototype.format(0);
---

And:
---
Object.prototype.localeMatcher = "invalid"; 
Intl.Collator.prototype.resolvedOptions();
---

And:
---
Object.prototype.localeMatcher = "invalid";
Intl.Collator.prototype.compare();
---
