I'd repot based on roots, if you think it is time. It is not optimal the leaf is like that, but just flop it over the sides as it gets bigger. Probably won't be long either way, so you shouldn't have to worry about any sort of growth from resting on the rim.
It'll get taller for sure. If that's the final pot, it'll definitely rise about at some point. The apical meristem(trunk) will continue to grow and older internodal spacing increases slightly over time.
In no time those branches will have to clear the same space to be relevant. That leaf will be 100% covered long before it's all said and done anyway. If it hasn't cleared and completely shaded later on, remove it for airflow.
