Thanks for taking your time to report this issue and help making Ubuntu better.
When comparing the two different veresions, see [1] and [2], it looks like the underlying reason is that libgles1-mesa is no longer built so there's no newer version to replace the old one. I believe I have seen other bug reports regarding libgles1-mesa missing from newer mesa releases, but I can't find those at the moment, nor do I know if it has been intentionally removed.
