Yes it will stop if it's outside of it's following error parameter. You are loosing steps for a reason not because steppers are inaccurate. That reason will still be there unless you change something like use larger motors or change the tuning setup. Closed loop system will correct for some error before it reaches the following error threshold but still error happend and if while in the cut material will be lost.!

In your case with only happening on occasional Rapid moves then Closed loop probably will correct the error rather than fault. But thats an awful expensive route when just buying correct size steppers/drives and/or tuning motors correctly will give you exactly same results.
