i18next - namespaces not picked up, <Trans> not pickedup up

[VinzentE]

Some variants are not beeing picked up by ally.

Example 1:
const title = t('someNamespace:title')

The notation {namespace}:{key} is not detected.

Example 2:
This variant is being picked up
field.time.description

But this variant is not
<Trans i18nKey={'field.time.description'} />

Any ideas? Is that due to wrong settings or missing support or a but?
