This bug is not fixed as of 1.20.6. It is also present on 1.20.1 and 1.21-pre2 (and more, just not tested), but is not present on 1.8.9. Changing the locale, system or otherwise, does not fix the issue in this case. I have tested with en-US, en-GB, and en-IE. None fix the issue, but I doubt this bug is very reproducible.
