[Koha] Not able to change framework when editting biblio record

[Pedro Amorim]

Dear all,

I just recently updated our Koha from 3.22 to 16.05 and now we cannot
change from whatever framework the record is (editting or creating new one,
same behaviour).

The following javascript errors are thrown in the console:
1) Uncaught SyntaxError: Unexpected token =       jquery.fixFloat.js:6
2) TypeError: $(...).fixFloat is not a function

The 1) error is the one causing the problem since 2) is only happening
cause of 1).
This is a syntax error happening in the js file and this behaviour can be
reproduced in the Tamil online public demo (tamil/tamil):

https://kpro.tamil.fr/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=1&frameworkcode=&op=&searchid=scs_1475082520244#

Try to change the framework, nothing happens. And the errors in the console
are the same as described above and happening in our instance.

I rolled the file back to commit 262 as seen at:
https://github.com/Koha-Community/Koha/commit/2628fdd8c4f8bb6f5d5d6a8f35646435ac1a1775

And now everything is working fine.

Why is this happening though? Any thoughts?

Thank you,

Pedro Amorim
