plot() with ols_step_both_aic() doesn't show anything when AIC values are negative.

[williamlai2]

I provide a reprex for this as the object doesn't seem to be able to be written out properly, but when the AIC values are negative, then plot() doesn't work properly. The limits need to be manually reversed.
