well, generally the bot is right, but in this specific case we are comparing |width| and |height| with '0', which makes the code easier to read for me than using "!width", so i would not bother much , unless someone (reviewer) thinks different.

otherwise, lgtm.

I would have used frame and coreFrame :-)

What is with is 0, but height is not?

I assumed the method will calculate using 0 for width and a given value for height, and it will possibly return a invalid value for that.
