Description of the issue

When using @ in a document, a list appears with employees, issues, documents etc.
In this list only 5 issues and documents are shown, which makes it often impossible to add a link to the correct issue.

Your environment

• DuckDuckGo and Chrome (latest)
• Mac OS

Steps to reproduce

1. Open the Documents menu
2. Create a document
3. Type @ - a list of employees, companies, issues,. .. documents appears

=> This list is limited and not loaded on demand when typing extra characters

Expected behaviour

A list of issues that is updated / filtered when typing some characters after the @

Actual behaviour

• The list shown is not complete
• When typing some characters after the @, most of the time, there are no results because only the issues from the initial list seem to show up
