Extracted from #111335. We have a plenty of coverage for this under libraries.

These two apparently failed a few times in past: https://github.com/search?q=repo:dotnet/runtime+b15307+OR+b04914&type=issues, there are others which have never reported failed since the initial port (e.g. under JitBlue among other places).

These are among the few tests under src/tests that exercise System.Globalization APIs. They are likely to fail when System.Globalization APIs are broken. We have a plenty of tests that cover System.Globalization APIs under libraries, and we prefer API tests to be under libraries in general.

I assume that vast majority of tests never failed (in main). It does not mean that it is ok to delete them. The question to ask when deleting tests is whether the coverage is redundant.

[am11]

True, but the ones which have reportedly failed slipped though the cracks. Maybe it hasn't happened since the monorepo convergence because of live testing, so they are covered.
