Need "symbo-alt-narrow" for Int.NumberFormat options.currencyDisplay

[zincli]

new Intl.NumberFormat('th', { style: 'currency', currency: 'THB', currencyDisplay: 'symbol' }).format(130);
// "THB130.00"

new Intl.NumberFormat('vi', { style: 'currency', currency: 'THB', currencyDisplay: 'symbol' }).format(130);
// "฿ 130,00"

Even though this is defined in the CLDR, I'm still not sure if it is a expectation for "symbol".

So I'm thinking that we could use the "symbol-alt-narrow" defined in CLDR to match our product's requirements.

This is covered as part of

https://github.com/tc39-transfer/proposal-unified-intl-numberformat

Will be available in currencyDisplay: "narrowSymbol"

CLDR was changed to use "฿" for Thai.

But apart from that change, the "narrowSymbol" option is now available, too.

js> print(new Intl.NumberFormat('th', { style: 'currency', currency: 'SYP', currencyDisplay: 'symbol' }).format(130))       
SYP 130.00
js> print(new Intl.NumberFormat('th', { style: 'currency', currency: 'SYP', currencyDisplay: 'narrowSymbol' }).format(130)) 
£130.00

Yep, the proposal is Stage 4 and merged. Closing as Fixed

Has this been released yet?

I am on FireFox 77.0.1 and getting thrown this error:

This feature will be available starting Firefox 78 (release today, not sure if automatic updates have already started).
