Here are the steps to reproduce:
- Create a user named Social01 Office01 User01
- Add the user as a connection
- Go to Microblogs
- Type @Social01 Office01 and click on the name in the dropdown to add a tag. Post the Microblog
- Type @Social01 Office01 User01 and click on the name in the dropdown to add a tag. Post the Microblog
The tag should display with no additional text.
The tagging process leaves behind excess text. At step 4, the middle name is repeated. At step 5, the middle and last name are repeated. This does not occur if the tag is added after only typing the first name. See attached gif.
