I recently encountered this when I was retrying a UDP send. I was getting ERR_BUF errors then realized any added headers down the chain (UDP->IP->etc) weren't removed on failure.

I'd count this as "intended behaviour". While this isn't too cool to be a feature, it actually makes the stack smaller because you don't need all the "revert on error" code. It's been like that for ages now...
