Hey, a cursory search revealed no feature request to this issue that I would consider a borderline bug:
When a user copies text into Hype it may contain style elements, depending on where it originated. This has confused a lot of users in the past, with offered solutions ranging from "copy into notepad first" to "paste it into an email" to strip a text of unwanted style attributes.
The style attributes can really wreak havoc with a design within Hype, especially when they overwrite the global styles the user tries to apply to the text through the Hype UI. Only when the (power) user double clicks on the element containing the text to reveal HTML-source, can one see the trouble-causing elements. It confused the hell out of one of my students recently, and the workaround to get her to turn all the text she pasted into plain text after the fact was really cumbersome.
Would it not make sense to have Hype strip all pasted text from styles? Or at least offer a way to do so from within the app like "reset all styles on element."
