Is "omitted text" the title of that conversation, or did you change it? I'm guessing the latter and the conversation title actually has something to do with advertising in the text.
Unfortunately, there isn't too much more we can reasonably do about this. This is an issue with ad blockers and, to a degree, how they interpret fetches from service workers. uBO in particular always treats them as "ajax" requests and can't distinguish a top-level navigation and thus it applies some more aggressive rules. (In Chrome at least, I'm pretty sure that the JS does know whether it's a top-level navigation, I'm not sure whether uBO could react to this.)
We actually have a couple rules where we bypass the service worker-based fetch if the URL contains specific keywords (to avoid various SW-related browser quirks), including a couple of ad blocker ones, but expanding this net wider also starts to defeat the purpose of using a service worker (and could invalidate the PWA installability checks, as Google has suggested they are going to tighten these validations in the future).
