This would incorrectly also escape commas actually present in fmt.
I guess a simple-ish solution could be to str.split fmt over commas, apply locale.format_string over each part, escape resulting commas over each formatted part, and join again using unescaped commas.
Edit: basically
return self.fix_minus(
# Escape commas introduced by format_string but not those present
# from the beginning in fmt.
",".join(locale.format_string(part, (arg,), True)
.replace(",", "{,}")
for part in fmt.split(","))
if self._useLocale else
fmt % arg)

This test will fail with "unsupported locale setting" if the locale is unavailable; at least this should be caught, and it may be better to just monkeypatch locale.format_string instead?

PR Summary
When creating a plot with a locale where a comma is used as the decimal seperator and with useMathText enabled for ticks, an unwanted space is added after the comma (Example: "3, 0"). This PR addresses this issue #23626 by adding an escape around the comma in a formatting method for the ticks.
