Good catch. Although, when comparing an issue that affects no modern browser against an issue which affects all modern browsers, the issue which affects all modern browsers is perhaps a little more important.

And when there's a solution that is trivial to implement, and can fix the issue for two existing major modern browsers (probably more to come), it might not be a completely crazy idea to go ahead and implement it.

P.S. Thank you for graciously gifting me the final word
