It seems it is simply a rendered form output that doesn't match the expected one. One of the reasons seems to be an string/Unicode mismatch and the other
is this one:

​http://paste.pocoo.org/show/260082/

The expected output was introduced in [13578] when backporting [13577] by blindly copying it from trunk, it contains a helptext span that is present there but not in 1.2.X (see r13519/r13522).

(In [13707]) [1.2.X] Fixed #14247 - 'forms' test failure in 1.2.X
