Weird behavior on iframe using iOS version of my app

I’m trying to implement an iframe into a section of my app.

In Android it’s working fine but on iOS when you do scroll the page on the iframe reloads, you cannot do the submit in some forms.

I don’t know if this is the normal behavior or I’m forgetting something. I’m loading the iframe under DomSanitizier.

Any ideas?

Update: In iOS i have this message: Blocked a frame with origin “http://localhost:8080” from accessing a frame with origin “”. Protocols, domains and ports must match

I know it’s something related to the cross-domain, but I cannot find the way of doing this well
