Reproduction steps:

1. Start the server.

2. From Admin --> Content --> Blogs, add a blog and add a tag "Chrome-test" to it in "Categorization" then publish it.

3. Add another Blog then add a tag "Chrome" by clicking on Enter.

Actual Result: When click on Enter the previous tag is added.

Expected Result: Adding new tag that has portion of the previous one should be possible by clicking Enter.

The cause of the error is that in the autocomplete drop-down list the tag "Chrome-test" is autoselected. Pressing Enter will attempt to insert this autoselected tag.
