 Background: [746/tests], [747/tests], #19861.

 `Tests_DB::test_locale_floats()` ensures that floats formatted as `0,700`
 get sanitized properly by `wpdb`.

 This is relevant for locales using comma as a decimal separator: `ru_RU`,
 `fr_FR`, `de_DE`, `es_ES`, and others.

 [43359] / #43829 added `ja_JP` to the list. Per
 [https://en.wikipedia.org/wiki/Decimal_separator Wikipedia], Japan uses a
 dot, not a comma, as a decimal separator, so adding it here doesn't seem
 to serve any purpose and might cause some confusion.
