Blink walk problem

Hello i would like to ask is this a bug? or it is designed that way. After i use blink and use a spark sometimes my character start walking instead of runing and its wallking until i use the spark or any other skill again it a bit anoing not a bit a huge anoing actually, could this can be fixed?

bump

can consistently reproduce (~80%, timing based) by casting spark twice (x2 press, not hold) instantly after blinking

I've been experiencing this as well, playing on mouse and keyboard.
