Don't know about jealousy tbh but it's definitely small time. Don't know too much about Welsh-English relations but I don't see what there is to celebrate about, that'd be OTT even for the Scottish or Irish.
There are a few national teams that I love seeing fail but I've never even remotely celebrated one of them going out like that, and unlike certain platinum haired blokes I'm not even friends/team mates with one of those who went out.
Potential Adebayor-Bendtner moment coming up next season
