Can't use 1st ability while crouching/sliding to the right

[PalePhoenix]

As stated in the title, shown in attached video by pressing 1 while moving in each cardinal direction. Applies to every tested hero, discovered while playing Vyper. Would like to know if replicable by other users, otherwise might be an issue with personal settings or Windows.

Confirmed that rebinding either of the keys--'Ctrl' for crouch and 'D' for strafe right--allows for the first ability to be used. Additionally, every other ability can be used while holding Ctrl + D, only the first ability does not work.
