"invisible filters" occur when the mapping chain throws an error. If a single filter throws an error, the entire chain rejects. As a result, not even the valid filters appear in the filter bar because they never get added to the scope. However the filters still exist in app state and still get sent with each search request. The most common error occurs when the filter's meta.index property points to a non-existing index pattern. Since this property is only used for looking up field formatters and it is not essential for a working filter, we now fall back on raw values instead of failing if the index pattern is not found. See the PR this one replaces for discussion about other solutions we tried and why we chose to go this route.
