Icon not show on mobile app if horseshow are in conditional card

**Home Assistant**: 2023.9.3
**Frontend**: 20230911.0
**Home Assistant Mobile App**: 2023.4

I created a condition card with the horseshow card nested.
In the mobile app the icon is not displayed, however in the desktop browser it works correctly.

Ex.
The card is not working properly (the icon does not appear in the mobile app):

The card works correctly (icon also visible in the mobile app):
