We noticed a significant bug in the Katalon BDD - Test Automation for Jira app for Jira Server.
It injects into every Jira page an obsolete version of the popular CodeMirror online editor. This, in turn, breaks multiple other popular Jira add-ons such as ScriptRunner, JMWE, JMCF, etc., that also use CodeMirror.
CodeMirror (and in general the Katalon “all” JavaScript file) should only be injected into Jira pages where it is actually needed, not into all Jira pages.
