[GAMEPLAY] Sylas unable to use his E at all after dying in stolen Elise's rappel

Playing as Sylas after stealing Elise's ult, I died to her red buff + red smite while I was rappelled. After which I was able to use Elise's rappel one more time without having any of her other abilities. I was then stuck with Elise's E unable to use Sylas's normal E or the stolen Elise E. I was able to fix it by stealing the enemy Mordekaiser's ult and using it. When my Mordekaiser ult wore off it reset my E back.
