If it makes you feel better, these PMs are ruining development too: the developers can absolutely see that issue you referenced and were probably telling the PM they can knock it out in a few minutes or even started working on it already. PM will step in and say no, you do what's on the backlog. Developers lose all agency and start quitting. Product further deteriorates.

As a dev, the best kind of work is when you're connecting with your users and solving a real pain for them. Being robbed of these opportunities is how you get burnt out.
