>> Implementing "loose matching" of space separators in both `java.time.format.DateTimeFormatter` and `java.text.DateFormat` on lenient parsing. This will effectively fix the NNBSP issues on parsing time with am/pm markers introduced with CLDR version 42 (https://inside.java/2023/03/28/quality-heads-up/). A draft CSR has also been drafted.

src/java.base/share/classes/java/text/DateFormat.java line 751:

> 749:      * @implSpec A {@link Character#SPACE_SEPARATOR SPACE_SEPARATOR} in the input
> 750:      * text will match any other {@link Character#SPACE_SEPARATOR SPACE_SEPARATOR}s

LGTM.

Nit: Might read better as either "in the pattern with lenient parsing" or "in the pattern when parsing is lenient"
