window.ethereum not injected in iframes

[stephancill]

We're working on frames.fun, which adds farcaster frames to X using iframes - for some reason window.ethereum is not available in the added iframes we add to the page whereas metamask is.

Do you have any ideas around why this could be the case?

Maybe the content script load isn't triggered multiple times due to some deduplication by tab?

Happy to provide more details/repro if nothing comes to mind
