mergeLocalMessage broken?

[websanova]

Using merge after some delay does not seem to trigger an update.

Works

Vue.i18n.mergeLocaleMessage('en-US', {test: {one: 'one'}});
Vue.i18n.mergeLocaleMessage('en-US', {test: {two: 'two'}});

Does not work

Vue.i18n.mergeLocaleMessage('en-US', {test: {one: 'one'}});

setTimeout(() => {
    // trying to output {{ $t('test.two') }} does not work it never triggers in this case...
    Vue.i18n.mergeLocaleMessage('en-US', {test: {two: 'two'}});
}, 2000);

Works with "set"...

Vue.i18n.mergeLocaleMessage('en-US', {test: {one: 'one'}});

setTimeout(() => {
    Vue.i18n.setLocaleMessage('en-US', {test: {one: 'one', two: 'two'}});
}, 2000);

EDIT: Not sure if it's related to latest change #1099 ?

I can confirm it is a bug due to #1099 and should be fixed asap.
Added a PR. #1321

close, as reason, vue-i18n was released.

Thanks
