I don’t know if this behaviour is intended, but every time I refresh the page, all old hot-updates are applied to the page. So after updating the stylesheet 20-30 times, the page applies all the changes.
This isn’t a “real” problem, but the screen flickers and rending takes some time (if the stylesheet updates were large). So is there a way to disable this? The CSS should be inserted just once after reloading the page, shouldn’t it?
