Can't use this with custom:banner-card

[Miguel R]

My Home Assistant version: 0.97.0

My lovelace configuration method (GUI or yaml): yaml

What I am doing:
trying to display a custom:dual-thermostat as a popup while using custom:banner-card to display my living room entities.

What I expected to happen:
a dual thermostat card appear

What happened instead:
no custom:dual thermostat card just the normal climate card for 1 of my entities

Minimal steps to reproduce:
Well I would say you need to have the dual thermostat, banner card, and try the pop. Can't see how else to reproduce. Maybe with a custom card?

Actually upon further playing with it I have noticed that the issue is more that the dual-thermostat card is too small. This is what appears

it should display like this:
