Fixes the behavior described and shown in a video here: #2239 (comment)

@pearcetm Thank you for the additional description and the video. This is definitely an improvement! I feel like we wrestled with this code for a good while in #2160; it's wild you could make it better by just deleting some code. 😆

I've played around with this a bit and it seems solid. @joedf Do you have any thoughts on this patch? Anything we should be testing before merging it?

Works flawlessly, I'd say even much better! I recommend merging it and including this as is.
Only a minor thing is adding an extra empty line above line 536 for consistent formatting.

@pearcetm @iangilman Thanks for getting this fixed and verified! This whole constraints thing has definitely been a bit of a headache for me. I'm so glad, I knew it could be shorter, but just too confused. hahah 😬👍

Awesome! Thank you for trying it out @joedf, and of course, thank you for making it happen, @pearcetm! Let's merge this! :)
