Raw Cr.ERROR don't get stack information, same as throwing JS literals instead of `new Error()`s. This was done automatically with a new eslint rule that will be introduced in the next commit. One instance of a raw Cr.ERROR was not replaced since it is used in a test that specifically checks the preservation of raw Cr values in XPCJS. The rule will be disabled for that instance.
