Bug: Offline Mattemost instance - Icon emoji preview not loaded due to unpkg.com reference on boards

[TheMasterFX]

Steps to reproduce the behavior

1. Install a Mattermost instance in an offline environment (no connection to internet)
2. Go to Boards => Create New Board (from any Template you like)
3. Open a Task
4. Click on the Symbol => Pick icon => Preview is empty

Expected behavior

Preview of icon is visible

Observed behavior (that appears unintentional)

No Icon preview visible due to reference to (hardcoded?) background-image: url("https://unpkg.com/[email protected]/img/apple/sheets-256/64.png");

Possible fixes

Make sheets-256/64.png offline available

Screenshots (optional)

Edition and Platform

• Edition: Personal Server with Mattermost Boards (plugin)
• Version: 7.4.0
• Browser and OS: Chrome + Firefox + Desktop App on Windows
