Scroll bar is not displayed on delegated rule 8.6.2
I have delegated Map Value rules in Pega 8.6.2 and tried to render the same using a mashup. On Edit of the delegated rule it opens in a modal dialog without vertical scroll bar. This issue is similar to the one discussed in the following URL : https://support.pega.com/question/scroll-bar-not-displayed-delegated-rule.
Unable to open the Support Article mentioned in the link.
Can you please let us know what is the local change suggested.
