Excellent idea! Why didn't I think of it?
Anyhow, the gap dissappears with the sanded biscuits, so all is well.
Now the only issue is whether I should add a third biscuit in the middle
that is cut deeper.

In the instance of using biscuits in mitered corners, the biscuits do add
considerable strength to the joint in addition to helping with alignment if
the joint is end grain to end grain or if the panels are plywood. The more
the better if the joint runs perpendicular to the grain.
