Cannot create pyReportingSkin
After upgrading to Pega 7.1.9, developers are no longer able to start the name of the property with 'py' and are unable to create a skin rule pyReportingSkin to style the Report Editor and Report Viewer.
Steps to Reproduce
Attempt to save-as pyEndUser71 as pyReportingSkin.
Refer to the product documentation: https://pdn.pega.com/updating-skins-reporting
In Pega 7.1.9, the Report Viewer takes its styling from the application skin, while the Report Editor should be customized by adding CSS code to the workform_pyreportingskin CSS rule.
