Hm, that will not work because the replay is in an iframe inside of a webcomponent and isolated from the rest of the page - (if it did, the ReplayWeb.page UI itself would also be disabled).
We don’t have a way of injecting custom css into the replayed page, but in theory, that should be possible. It has been requested before, but not frequently. @John1 if you don’t mind, can you open a feature request issue on our GitHub at: GitHub - webrecorder/replayweb.page: Serverless replay of web archives directly in the browser explaining what you’re trying to do.
Is the issue that those other links are not captured, and you want to avoid taking users to the ‘archive not found’ pages?
