Unable to Void Blast when Melee Attack and Quick Melee are bound to Scroll Wheel

[birdsandbeas]

Just what title says. Binding Melee Attack and Quick Melee to Scroll Wheel Up and Scroll Wheel Down seems to make it impossible to use Void Blast as your operator. Neither of the two input nor E work, and resetting to default controls when only changing that binding fixes the issue.
