Summary
I'm not sure what caused this issue, maybe this is introduced in #5724.
The problem is that "dnn.jquery.js" was loaded before "ScriptResource.axd" that includes the WebForms classes (with
Sys.WebForms.PageRequestManager
). To resolve this issue the events are now being registered after the DOM has been loaded. In this case the classes are loaded.
