Diamond Dive - boost gets stuck

[tafode]

If the player flies to the edge of one of the "pools" and just short taps the space bar/boost, it get stuck and loads up to full power without having the button pressed. If the player then taps again it the ship boosts and immediately the boost bar starts to fill up again without pressing anything.

I tried to fetch the Keyboard Input and the gameplay in this Video, bug starts around 39 seconds:
