What problem does this address?

When a post is published, users are presented with View Post links that open the published post. This view reflects what the audience will see and is distinct from the editor interface. For this reason, it makes sense to open these links in a new tab, preserving the editing context.

Consider the following user flow:

• A user creates and publishes a post. They click View Post to quickly preview it, intending to return and make further edits. However, the post opens in the same tab, replacing the editor and disrupting their workflow.

Comparing this with other parts of the editor where the behavior differs:

1. After saving a post, the snackbar notification includes a View Post link that opens the post in a new tab.

2. In the Post Settings panel, next to the post title, the editor-all-actions menu includes a View option, which also opens the post in a new tab.

Before testing the above conditions, ensure the preference Enable pre-publish checks is enabled.

Clicking on the View Post button within the Post-Publish Panel should open the post in a new tab.
