at issue

I'm a little stuck... Click here to teach me more about this clue!

'controversial' is the definition.

'sounds like sneezing is' is the wordplay.
I cannot really understand how this works, but
'is' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
