Android JSC Intl do not support signDisplay option

[retyui]

Description

I enabled JSC with Intl support:

// android/app/build.gradle
def jscFlavor = 'org.webkit:android-jsc-intl:+'

Then try to format currency with a signDisplay option

Intl.NumberFormat('en-US', {
        signDisplay: 'always',
        style: 'currency',
        currency: 'USD',
}).format(12) // $12.00

And result is $12.00 is incorrect !!! should be +$12.00

Deps:

yarn list jsc-android
