Subject: [PATCH] Fix the `gStateObj` lookup in
 `TranslatedFont._removeType3ColorOperators` (PR 12718 follow-up)

As can be seen in https://github.com/mozilla/pdf.js/blob/2cba29036180b420778bd2c91d21d71bd207c146/src/core/evaluator.js#L986 the `gStateObj` (which is actually an Array despite its name), is wrapped in Array when it's inserted into the OperatorList. Hence we obviously need to take this into account when accessing it in `TranslatedFont._removeType3ColorOperators`; this mistake happened because we don't have any test-cases for this particular code-path as far as I know.
