I have a Scriptrunner Fragment/Rest API combo that I have been using to put a button on the Admin->System page. When the button is clicked, it displays the dialog generated by the Scriptrunner REST endpoint. This has all been working fine for quite awhile.
After a recent Jira upgrade (I guess), when I click the button, the dialog doesn't open modally, it opens as a full page. There are no CSS libraries, or jquery, or anything loaded in this new page so nothing works.
If I move this button to an issue page - putting it in the jira.issue.tools location, it works (opens modally) fine.
It seems like the fragment isn't working on Admin pages. Is anyone else seeing this? Has something changed that I missed notification of?
