When pressings spacebar during a comment it stops and starts the video

After the latest update since about 2 to 4 weeks ago I can no longer leave a comment on uploaded videos for review without the spacebar stopping and starting the video every time. For example, I want to comment on the video at exactly 15s into the video, but when I start typing my comment, every time I hit the spacebar it starts playing (and stops playing) again so by the time I finish my comment the video is at 45s.

This is fixed now. Would love to know if Monday fixed it and if there was any update on it somewhere that I missed? Thanks
