Is there an existing issue for this?

• I have searched the existing issues

Have you tried deactivating all plugins except Gutenberg?

• I have tested with all plugins deactivated.

Have you tried replicating the bug using a default theme e.g. Twenty Twenty?

• I have tested with a default theme.

Description

The Navigation Block's Page Link Block still shows the option to create a draft even when a page with the same title exists. This could lead to duplicated pages with the same title, which seems unnecessary.

Step-by-step reproduction instructions

1. Add a navigation block.
2. Add a Page Link block and start searching for a current page title.
3. Notice that the create draft option is still visible even for a page title that exists.

Expected Behavior

I expect to not see the option to create a draft when searching for a page whose title exists. I think it would be better if it only showed when you continued typing a new page title that's not currently available.

Current Behavior

The create a draft option still exists.

Screenshots or screen recording (optional)

Visual of the problem where I have a page already published titled "Tuition" yet when I type it in the option remains to create another draft with the same title:
