approach to corners 45 deg to grain direction

I have parts to cut out (I made a quick diagram attached) and I'm not sure how to approach the corner sticking out at a diagonal to the wood grain direction. I'm cutting in oak right now which is maybe the worst in terms of grain splitting but I also get the problem in walnut.

It breaks a triangle off the end about 25% of the time.

I'm climbing milling and slowing down from 140ipm to 35ipm around the corner with an 1/8th inch depth of cut, honestly I'm not sure what else I could try.

Wondering if anyone has experience with this type of shape.
Thanks!

So two years later and still having this issue! wondering if anyone might have some thoughts on the matter.
