| bug1799980-healow.com-infinite-loop-fix.js |
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.
