Comment (by fishtron):

 I tried updating the unit test and discovered a couple of things:

 1) The patch might have some unintended consequences. Since it checks for
 the user locale, the dashboard is changing the default date/time format
 based on the user's locale rather than the site's default locale. This
 might not be what's intended and/or might not be what the user expects.

 2) The code for changing options is not unit-testable because it is
 written procedurally in the options filter. Currently it can only be
 tested with end-to-end testing, unless the admin options functionality is
 rewritten.

 (With help from @pbearne and @desrosj at WCEH 2025 Contributor Day!)
