 FAILED test: ../../dojo/tests/i18n.html::ungrouped::extraLocalesAsync 145 ms

Tested on IE8 and safari/mac.

Test was added in [25585] (when it worked correctly), but started failing with [26631] (so it's broken in 1.7 as well as trunk).

Marking for possible inclusion in 1.7.1 although not sure how serious this is.

In [27774]:

improved sniffing of i18n bundles in backcompat mode; fixed test; refs #14375; fixes #14222; refs #14226; !strict

In [27776]:

missed file should have been part of [27774]; refs #14226'; !strict

[Rawld Gill]

This has been fixed and backported as part of [27795]
