I increased the size of hat using the controls, and it
not looks great everywhere! Is it a bug feature?
and also it hides the "recent reviews" link & non clickable.
Hats are magnificent, mysterious, and most of all independent beasts. Who are we to dictate the bounds in which a hat must be confined?
While it's not on me to devalue the epic truth in Mrs. Hairboat's realisation that we don't "dictate the bounds in which a hat must be confined", let me put it this way: Yeah we do.
You cannot go too wild with placing & sizing the hat. But a certain amount is allowed, and I don't see a problem with your screenshot. In particular, all "recent reviews" links look at least partially clickable, so it shouldn't be causing issues. In some places we do shift content around if the hat would cover it otherwise, but right here it seems fine.
