Path_selector widget required true is not working

I’m on OnDemand version: 3.1.1 Can I patch it in 3.1.1 ?

Another weird behaivor I see with path selector widget when I make it hidden, it hides the text filed but not the button.

I reported it here:

Cluster specific modules don't populate in form.yml.erb

I cleaned my browse cache and I tried incognito mode and it didn’t help. My OnDemand version: 3.0.3. Is it better in a new version or do you see it in all versions? And I can replicate this issue as well. I have an older version of Ondemand 2.0.32 and I see path selector error there: #<ActionView::Template::Error: undefined method `path_selector’ for #BootstrapForm::FormBuilder:0x00007f2d18de7c58> Was path selector only intorduced recently?
