When publishing existing content (creating new version) with the PAPI, the publication date of the content gets the current datetime, same as modification date. While modification date behavior is correct, the publish date of the content should remain unchanged to reflect the original (first) publish date of the content.

Publishing from legacy administration does just that - changes only modification date.

To reproduce:

• load content
• create draft
• modify content with updatestruct
• publish new draft

Expected outcome: original content and republished content have the same publishedDate but different modificationDate

Actual outcome: republished content has different publishedDate than original content
