We cannot trace the chain of events from an applied element hiding filter -> injected selector -> blocked element. So the best we can do is looking for which injected selector there is a hidden element on the page, and then find a filter that is active on the given domain and has the same selector. Some edge cases giving inaccurate results might be inevitable. However, maybe a workaround for this particular case could be if we have multiple candidates to prefer domain-specific over generic filters.

Good idea, preferring domain-specific filters should be sufficient to avoid this issue.
