You should just be able to do
return empty( $values['width'] ) && empty( $values['height'] );There was a problem hiding this comment.
Also, if you really need all of these checks, then it might be easier to read stacked in a single if statement

| return true; |

So if the values are set but one of them is not numeric, the group should be considered empty?

The current lack of
group_is_emptyallows for cases where ad-layers will save an ad unit size as 0x0. This size group then becomes impossible to remove. This PR ensures that any sizes groups that have a 0x0 ad unit will not be saved.@mboynes / @bcampeau: For backwards-compat reasons, is there any use-case for an ad unit being 0x0?
