How can i fix troubles in iFrame content displaying?

[Max_Shesterkin]

Hello, everyone!

I create few iFrame widgets in Widget editor (in dev-hub) wich insert web-pages from: 

• Confluence;
• JIRA;
• Business Studio.

When I insert JIRA-iFrame, Qlik Sense can display part of content from it and part of the displayed buttons don't work if i try press them via Qlik Sense list.

And if I insert Confluence or Business Studio iFrames,  then Qlik Sense display only white list (example in attachements).
