Description

Gutenberg editor is stripping off the nofollow relation on links when the content is being copied from an already published content.

For example, assume I have a published content, where there is a link in the content. The link is set as 'nofollow' and 'open-in new-tab'.

• Now copy the content from this published post and open a new post in GB editor.
• Publish this new post.

Output
The nofollow link part is stripped. But open in new tab is retained.

Step-by-step reproduction instructions

1. Take a published post where links are set as nofollow.
2. Copy that content with link and paste it on GB editor.
3. Publish the post, and notice the nofollow rel are removed.
