Description:
------------
I think this is related to bug #65572.

CURRENCY_SYMBOL is taken into account when using format(), but not when using formatCurrency(). See example below.

Test script:
---------------
$formatter = new \NumberFormatter('en_US', NumberFormatter::CURRENCY);
$formatter->setSymbol(NumberFormatter::CURRENCY_SYMBOL, '@');

echo $formatter->format(1.2), PHP_EOL;
echo $formatter->formatCurrency(1.2, 'USD');

Expected result:
----------------
@1.20
@1.20

Actual result:
--------------
@1.20
$1.20

The ::formatCurrency() method expects the $currency parameter to
be:

| The 3-letter ISO 4217 currency code indicating the currency to
| use.

Exactly that is what's happening.

Indeed, and that's exactly what I'm passing to the method.
But setSymbol() should overwrite the symbol, whatever the currency, shouldn't it?

IMHO, that wouldn't make sense. ::setSymbol() sets a default, but
the $currency parameter of ::formatCurrency() overrides it. That
appears to be pretty common, cf. mb_internal_encoding() and
mb_substr(), for instance. If you want to use the default, don't
set the $currency parameter, i.e. use ::format().
