I don't think it's a bug because sometimes one might want it to be active.
In any case, use the Active option if you don't want it active.

Row[{"Press in an Emergency: ", 
  Invisible@PasteButton["The Button", "Send Help!", Active -> False], 
  " Between 9 AM and 4 PM"}]

You can send bugs to support at

According to the docs:

"Invisible[expr] displays as space that is the same size as the
formatted version of expr."

I was surprised to find that a Button within Invisible is actually
still active, although invisible.
I think a note on this behavior should be added to the documentation.

Is there a way to submit a "bug" report to Wolfram?
