iFrame is not working in non-Service worker mode

[benoit74]

This issue is closely related to https://github.com/webrecorder/wombat/issues/158, but still a bit different so I'm opening a distinct one.

Problem occurs in warc2zim where we use wombat to replay inside the ZIM.

Page where the problem occur is https://womenshistory.si.edu/events/mysterious-mrs-nixon

Test WARC and ZIM with only this page can be found at https://tmp.kiwix.org/ci/test-warc/women-history/

Problem was first that the iframe was not rendered at all first (because we inadequately set the isSw: true in wombat setup. This is known that we need to set it to isSw: false for warc2zim 2.

Despite setting it to isSw: false (which is the case in test ZIM), we now have a weird iframe content. WARC is working on replayweb.page, so this is clearly not a crawling issue.

I need help to investigate/fix this issue.
