Using Search Context List(by Special GitLab References) , and diappear situation..

First, I'm not good at English.. I used google translator.. please excused me. :(

Summary

I tested 'Search Context List by Special GitLab References (e.g. #issue_text)'. I saw the 'Search Contenxt List' disappears when I perform a few actions.

1. Input space bar
2. Input Korean language. (I'm Korean :)

Steps to reproduce

• Input space bar

  1. Go to Issues
  2. Make search samples Issues
     • now, "Test First", "Test Second", "Test Third"
  3. Move New Issue Page.
  4. Input Issue "#Test" in Description. (> Show 'Search Context List')
  5. Input white space next to "#Test". (> Disappear 'Search Context List')
  6. And, try to input more text. (> It has continued to disappear.)
  7. Delete all of the after the "#Test" text. (> Show 'Search Context List' again)

• Input Korean language.
  skip text.. I will show you a video next. I will search 'Test테스트' SearchContextList_ToInputKorean

What is the current bug behavior?

• Input space bar

  Steps to reproduce - 5. (> Disappear 'Search Context List') Steps to reproduce - 6. (> It has continued to disappear.)

• Input Korean language.

  Disappear 'Search Context List' to use Korean language. (but completed word is Worked when input Backspace.)

What is the expected correct behavior?

• Input space bar

  continue to seeing the "list" until I can not find any Issues.

• Input Korean language.

  'Search Context List' is work when input Korean language.
