fix: Make iframe loading more stable
Apparently the cookie banner breaks our GitLab UI iframes. Why? Nobody
knows. They seem to monkey-patch document.createElement and register a
mutaion observer to watch all iframe, img, embed and video tags. This
replaces src with data-src until someone accepts the cookies.
Funnily enough our iframes remain broken, even if cookies have been
accepted. Why? Nobody knows. Googling around a little, it seems like we
can fix this issue by slapping data-ot-ignore and the class
optanon-category-COOO1 on our iframes. Why? Knowbody knows. But it
should work.
Closes #1395 (closed)
