Entities with unchanging statistics stops the page from loading on Firefox

Checklist

• [x] I updated the card to the latest version available
• [x] I cleared the cache of my browser
• [x] I verified that I'm really running the lastest version in my browser console
• [x] I checked if there is another issue opened with the same problem

Describe the bug If you attempt to graph an entity using the statistics option and the entity has not changed for the period of time displayed then Firefox browser hangs. Google chrome fares a little better, it slows but eventually loads an empty graph.

Version of the card Version: v2.1.2
