Blink slows movement speed until next blink/dodge roll (SPACE)

occasionally after blinking, i will be slowed down to a walking speed and it will not be fixed until i blink again or dodge roll. I can't find any part of the blink description that covers this, so I'm assuming that this isn't an intended feature. it's not the absolute worst game breaking bug ever, but it is very very annoying when mapping. I've died quite a few times because of this already.
