I don't know about the inner workings of this particular issue here, but
turning the filesystem to RO when errors are encountered - isn't this what the
"error-behavior" flag controls?

$ tune2fs -l /dev/sda1 | grep ^Err
Errors behavior:          Remount read-only

Setting this to "continue" or "panic" should have avoided that whole "RO"
situation, I guess.
