Dateformat not localised

The DateField plugin in the CMS editor in View Mode takes the locale into account, but not sufficiently.

org.hippoecm.frontend.plugins.standards.datetime.DatePrinter.JavaDatePrinter#print(java.time.format.DateTimeFormatter)

ZonedDateTime dateTime = ZonedDateTime.ofInstant(this.instant, this.zoneId);
formatter = formatter.withLocale(this.locale);
return dateTime.format(formatter) + this.getSuffix();

This correctly identifies my location as being Europe/London, but then uses the Locale "en" to load the formatter. This results in the US date format, rather than the UK date format. One of our UK customers noticed this and would like this fixed.

Notice:

dateTime.format(formatter.withLocale(Locale.ENGLISH)) = "August 4, 2021 2:11 PM"

whereas

dateTime.format(formatter.withLocale(Locale.UK)) = "04 August 2021 14:11"
