It's not like computers give people a good reason to read the error popups. 90% of them these days are just "oops, computer pooped itself, a well trained army of monkeys is on its way to clean it up; try again later <tinyprint>0xbunchofbullshit-hexadecimal-uuids-for-vendor-telemetry</tinyprint> ;-)" anyway.
Most of the time, people are given only two options: give up on their task, or ignore the popup. No point in reading the message in such cases, it brings zero value.
I'd say the problem is that delete usually has a popup. Sure you don't really want to delete without any kind of confirmation, way too many people would click something on accident and if there's not a way to undo it (which has it's own issues), then a popup is a simple solution, but it does result in this unfortunate behavior.
