I'm pretty sure this is a bug. Auras don't size based on the token's dimensions. They only size based on the width of the token. This can cause some oddities for non-square tokens.
Occurs with both square or circular auras.
If this gets fixed/isn't the intended behavior, it should probably also be applied to light emission as well, as it has a similar issue.
