Indeed, this does come up every so often. It generally doesn't come up on "common" pages, as we don't use tables particularly frequently.
It's mostly a side effect of a non-ideal approach to adding this link. There is an advantage relating to getting the exact width we want, but it comes with this. It's not something I'd see really changing in 1.x, but it could be something at a 2.x level (if the other trade off is worthwhile).
