There's 2 issues I came across with the accessible/hidden text in the WYSIWYG:
Users should be able to select a set of words with in a paragraph vs hiding the entire paragraph. An example use case of this would be where you could have a series of "read more" links where there was text beyond the "more", for example, "read more about the computer science degree program" where " about the computer science degree program" would be hidden.
After applying the accessible/hidden text format, I was unable to escape from that format and any additional text had it applied.
