In some instances, the `modifications` of `tags` hasn't been properly serialized as a Ruby array but rather as a string (I've seen `""`, `"[]"`, and `"[\"\"]"`).
This generates an error when we try to `filter_tags` and remove `hidden_tags` (which is an array) from `tags` which might be a string.
Internal ref - t/131126
I wasn't able to figure out the root cause of this so I reverted the behavior that was introduced ~6 years ago in f2c060bdf2
