Cannot use Doorman's door when using quick cast and press & hold

[boranseckin]

I cannot use Doorman's door ability with quick cast and with press & hold alternate cast.

When holding the ability key to see the placement of the door, Doorman lunges forward and cancels the ability instead. It is not possible to see if the placement is valid or if the second door is within range of the first one.

Additionally, holding the ability key after the first door is placed removes the first door from the game and resets the ability.
