Element Scroll is not Scrolling - Jira

Hi There,

Has someone tried to scrape Jira TestSet?
I dont know why, but webscraper was not able to scroll the page (not doing anything, just show the 'Data Preview')

It works perfectly on this page (https://forum.webscraper.io/) and other page

Sorry I cannot provide the link since its very individual. Can someone clarify this issue?
