Mystic Expansion and Compress Cooldown doesn't work with Audience Participation (Sinclair)

[🐸DeadlockPlayer123🐸]

Mystic Expansion and Compress Cooldown action doesn't work on Sinclair's ultimate. Or rather, it works on the ability itself, but not on the stolen ability. For example: try to steal Holliday's lasso and you'll notice that after you use it, the range doesn't increase and the cooldown doesn't decrease.
