When enabling text visibility and selecting a new text language simultaneously, a race condition can occur that allows multiple text streams to be loaded in the same text media state.
Tracking a sequence id, updates loadNewTextStream_ to only create a new text media state with the text stream from the last call to loadNewTextStream_.

Resolves: #4821
