Iframe not working on github pages

Does anyone know why this iframe element does not work: https://rikuslategan.github.io/Mobile-apps-with-Go/#/page/670810e8-46a6-4f5d-9364-90760ebe2ec8 it simply reads go.dev refused to connect.

The macro I am using as defined in config.edn:

"iframe" "<iframe src=\"$1\" style=\"width:calc(100% - 4px);height:650px\"></iframe>"

The macro is called from the graph: {{iframe https://go.dev/doc/install}} which works perfectly fine in my Logseq client

x-frame-options is set to SAMEORIGIN on a googleapis stylesheet that loads with the remote page. Could this be the problem? If so, it might be out of my hands.
