[admin_toolbar] 3.3.1 compatibility issues

Corresponding issue on Admin Toolbar: 🐛 Upset theme since update to 3.3.1 Closed: duplicate

Hello,

There is a side effect after this update.
For the dark theme, 3rd menu links appear gray.

I don't have the problem on version 3.0-rc2

I think it's caused by this change:

.toolbar .level-2 > ul,
.gin--dark-mode .toolbar .toolbar-toggle-orientation {
  background-color: var(--gin-bg-layer2);
}

.toolbar .level-2 > ul, was removed

@Fabsgugu we should have fixed this already in 8.x-3.x-dev.
