Fixed Discord ID is not copied on a trade page, only message "Copied ID" appers

Device: PC
Browser: Google Chrome
OS: Ubuntu Linux

Steps to reproduce:
1. Open trade/moser-s-blessed-circle-t24365.html (just an example with user having Discord ID set)
2. Click Discord ID button (which is "Sod#4570" in this example)
3. The message "Copied ID" appears, but it's actually not.

Anything else to add:
If you do same with Battle.net ID button (which is "Aidan#2487" in the same example above), you get all working just fine.
