Some Realms icons are rendered behind the button in the main menu, instead of not being rendered at all

The bug

In some cases, icons relating to Realms are rendered behind the third button on the main menu, perhaps to hide them. If a transparent or translucent texture is created for buttons, these icons can be seen again.

How to reproduce

1. Download and apply the attached resource pack

2. Look at the main menu

Expected results

If there were no icons on the realms button beforehand before applying the resource pack, there should still not be any visible.

Actual results

There are. In my case it's gui/sprites/icon/news.png, gui/sprites/icon/trial_available.png and gui/sprites/icon/unseen_notification.png.
