OK. You've got to work at it.

If the low-level rendering software reports reaching the embedding level 
restriction, editing software could make that information available. Not 
just for this case, but in general. But the head-room is rather 
generous, by design, so the situation is going to be rare. And therefore 
not worth adding a feature that needs resources to develop and test...

And besides, if you have dynamic content, who do you send the warning to?

No, you guys have convinced me that relying on the headroom built into 
the bidi algorithm in this case isn't as cavalier as it at first 
appeared to me.
