It’s like that for me too, but when I plug in the power cable it feels secure. However I agree it would be better if it didn’t wiggleNo problem here.
However on the subject of the power cable: I do not know if this is the case for everyone, but I've found that the socket which the power cable plugs into has a lot of wiggle and give. I am worried that the clips holding it in place may break if I'm not very gentle with it.
I feel it would be nicer if the power cable was more securely fastened.
