ArcGIS Pro is much better at not cancelling the drawing of your map than ArcMap. However, it still happens:

What's worse is that there's no indicator that this is happening as there is in ArcMap:

I'd like to see some sort of indicator, whether it's that same 'Canceled' label appearing somewhere or adding a new icon to that status bar that shows as a green checkmark/red cross type of thing. I could see the argument for a temporary green check appearing when it's done drawing, and a persistent red x if there are errors.
