I accept that, due to language limitation, continue must be within a loop “properly” i.e. “not nested in a function or class definition within that loop.”

while True:
  def f():
    continue # SyntaxError: 'continue' not properly in loop
  f()

What’s the significance of the difference at break, where the complaint is that it is “outside” loop?

while True:
  def f():
    break # SyntaxError: 'break' outside loop
  f() 

I see no relevant difference in the language reference.
