Unable to filter hosts from class page

I follow the menus to the classes page and try, from the hosts column I select the hosts link to filter to a list of hosts using a given class and get and error reporting that external method ‘search_by_depreciated_class… undefined method’ failed:

This had been working fine previously, recently upgraded to 3.2 which might have been the problem. Currently running with the rpm package foreman-3.2.1-1 / CentOS 7

This seems to be a bug with Safari so I have posted this on the Redmine support page… Bug #35478: Issues Filtering Class Based on Host - Foreman

Worked around the problem by using Edge instead.
