QLocale::toDouble() fails to convert a string with Latin "e" or "E" as exponent separator in Ukrainian locale

Using Qt 6.4.3 [QtTest library 6.4.3, Qt 6.4.3 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 13.0.1 20230318 (Red Hat 13.0.1-0)), fedora 38], the following command:

QLocale(QLocale.Ukrainian).toDouble("0,00000000000000000000000000000123e30")

wrongly returns:

(0.0, False)

while, using Qt 5.15.9, the same command correctly returns:

(1.23, True)

The same issue occurs using Qt 6.5.0 and in addition also simpler strings with the Latin "e" and Latin "E" characters as exponential separator (like "444,46e1", "444,46E1", ) fail to be convert by QLocale(QLocale.Ukrainian).toDouble()
