+/**
+ * Bug 1799980 - Healow gets stuck in an infinite loop while pages load
+ *
+ * This patch keeps Healow's localization scripts from getting stuck in
+ * an infinite loop while their pages are loading.
+ *
+ * This happens because they use synchronous XMLHttpRequests to fetch a
+ * JSON file with their localized text on the first call to their i18n
+ * function, and then force subsequent calls to wait for it by waiting
+ * in an infinite loop.
+ *
+ * But since they're in an infinite loop, the code after the syncXHR will
+ * never be able to run, so this ultimately triggers a slow script warning.
+ *
+ * We can improve this by just preventing the infinite loop from happening,
+ * though since they disable caching on their JSON files it means that more
+ * XHRs may happen. But since those files are small, this seems like a
+ * reasonable compromise until they migrate to a better i18n solution.
+ *
+ * See https://bugzilla.mozilla.org/show_bug.cgi?id=1799980 for details.
