Hi Mike!
Tabs is a challenge ??
Gonçalo is right, is related with layers z-index, but in this case I think is better change the overflow from tabs.
I suggest:
- Use position bottom right (outsystems UI entities)
- User the following fix, but pay attention can cause other issues, so if possible be specific for this tabs.
.tabs .tabs-header {
overflow-x: visible;
}

Regards
