Copy query button does not work

[edmundoa]

On Graylog 2.2.0, opening the show query modal dialogue and clicking on "Copy query" is not working as expected. This problem is not happening in all copy to clipboard buttons, the one copying the message ID is working.

Expected Behavior

Clicking on "Copy query" should copy the ES query to the clipboard.

Current Behavior

Clicking on "Copy query" does not copy anything to the clipboard.

Steps to Reproduce (for bugs)

1. Open search page
2. Click on More actions -> Show query
3. Click on Copy query
4. See that the query was not copied to your clipboard

Your Environment

• Graylog Version: 2.2.0
• Operating System: macOS and Linux
• Browser version: Latest Firefox and Chrome. The issue cannot be reproduced in Safari, though.
