More than six banner patterns can be added to a banner

The bug

It's possible to add more banner patterns after the making the 6th one by putting a different banner in the loom UI, pressing one of the banner patterns and swapping it to the banner that has 6 patterns and then you have a 7th banner pattern that isn't the ominous banner.

How to reproduce

1. Create a banner with 6 patterns.
2. On a second banner, select another pattern
3. Without taking the second banner out of the right side of the GUI, swap in the first banner
   The 7th pattern should now be applied to first banner.
