I've been trying to figure out some spooky 'why did my ticket priority change' issues and believe it is related to the behavior when a workboard is sorted by priority.
* Sort workboard by priority.
* Lackadaisically drag a card from one column to another.
* The priority of the task is changed based on wherever your mouse pointer happened to land.
I understand that this makes a certain sort of sense but the reason I sort by priority is because I **don't want to worry about sorting order**. Instead the actual priority changes which matters **even more** than the natural sort. This is exacerbated by the difficulty of scrolling with long columns (T5240).
It's also results in inconsistencies with the natural sort behavior: with natural sort dragging to the bottom of a column makes that task the least important thing in that column, while with priority sort it makes it tied with whatever is currently at the bottom (if everything is Normal you can't drag to Low).
