Description

Keywords within emailProvider.credentials don't seem to be preserved on export. Because credentials aren't returned when retrieving remote assets, the keyword replacement logic can't find the property on the remote assets object src/keywordPreservation.ts#L202. As a result it's never updated/set on this object and the keyword isn't preserved.

Expectation

Should have keywords preserved within emailProvider.credentials
