Intl.DateTimeFormat(...).resolvedOptions() always return 'short' in timeZoneName

[vitvad]

Version: tested for 9.21 and 11.60
Platform: OSX Mojave x86_64

tested with ICU v: '63.1', and without.

quick step to reproduce:

var region1 = new Intl.DateTimeFormat('en-US', { timeZoneName: 'long' });
console.log(`'${region1.resolvedOptions().timeZoneName}' should be equal to 'long'`);

will always return 'short'.

@srl295 Thank you for quick response.
I just checked node v11.12.0 and it has v8 version v8: '7.0.276.38-node.18',
could you please clarify when node build with new v8 will be available ? As I see in ticket above, original plan was - Dec 2018.
As I understand it appear in node v12 around 2019-04-23 ?

@vitvad Welcome. I'm not quite sure how to answer your question. You could ask on PR #23423 ?
