Hello.
We are not being able to use some features from JS like Drag and Drop in our tempo plugin on Jira Server, and after some investigations I realized that Jira 8.22.1 has the Atlassian Plugin WebResources Implementation in version 5.4.11 which is working fine.
After a customer upgrades for Jira 8.22.2 it's stopped working and the Atlassian Plugin WebResources Implementation is 5.4.13.
On the Jira 9 it is occurring the same problem and Atlassian Plugins WebResources Implementation is 6.0.1.
