fix the title side for odd cheaterslope situations

[alexcjohnson]

Fixes #2254

The mock I added here really highlights the fact that we don't explicitly include labels/titles in autoranging the containing axes for carpets... but that's outside the scope of this fix. Actually, this mock isn't even autoranged, or you wouldn't be able to see some of the titles at all! Mostly though this is only a problem for tiny carpets as used in these mocks, most real-world examples are just fine.

Anyway, before the fix this mock would have looked kind of like:

Ie some of the titles are just completely in the wrong locations.

@bpostlethwaite please review - I would like to get this fixed before we make a slider for cheaterslope that makes it super easy to access these conditions 😅

ah shoot, the failing airfoil mock pointed out that this doesn't work with showticklabels: 'none' - hold on, a little more work to do...

@bpostlethwaite ready for review

Good catch - 💃
Is there an issue for implementing the full autoranging behaviour for carpet axes titles/labels?
