I've recently had a few comments I was in the process of typing out wiped out when a new answer was posted to the question. I don't remember this happening before, but I don't recall if the conditions existed for it to happen before. It's difficult to set up the conditions for reproduction and testing, so:
- Has anyone else noticed this?
- Is this a new behavior? Is it intentional?
- Is it possibly browser-sensitive?
This behavior has survived a reboot, incidentally.
