Grails groups not expandable

Greetings,

I have just upgraded from 2022.1.4 to 2022.2 and noticed that when in Grails project view some of the 'groups' can not be expanded i.e. they are missing the '\>' icon and nothing happens when I click 'Expand All'.

Have a look in the difference for 'Forms 2.5.9' between 2022.1.4 and 2022.2 in the attached screenshots. In 2022.2 the 'Domain Classes', 'Controllers', 'Services' and 'Tag Libraries' can not be expanded.

Regards

Rune Hansen

Reproduce the issue in IntelliJ IDEA's Grails project view using the reported 2022.1.4 and 2022.2 versions, focusing on the Forms 2.5.9 groups. Inspect the plugin's handling of Domain Classes, Controllers, Services, and Tag Libraries; done means each group shows an expansion control and responds to Expand All.
