Back to topic:
Aha! from your first video/gif it seems to behave like that in your pc, in mine it does not, weird. I dont think it's a bug, most probably it's your machine performance? Mind if you specify your machine spec, OS, browser you tested. I tested in all browser and all seems fine.
Can you get your hand to other pc probably? Best thing I could suggest to help is try to export it, and run index.html. See whether it persist.
