Video playback speed does not appear to be working

When setting up a new task I sued the reference task/layout for video classification.
I edit the layout `

```

I'm on Chrome.
Expected behaviour from docs: https://labelstud.io/tags/video#Parameters

[defaultPlaybackSpeed] | number | 1 | default playback speed the player should start with when loaded
-- | -- | -- | --
[minPlaybackSpeed] | number | 1 | minimum allowed playback speed; defaultPlaybackSpeed cannot be set below this value
