[Bug]: Icons missing on Desktop Browsers (Chrome/Edge/Firefox) but working on Mobile App

[jvnrambo]

Requirements

• I checked the troubleshooting section in the README to verify that I have the latest Mushroom version.
• I did a search to see if there is a similar issue or if a pull request is open.
• I have read the state of card mod support (in pin issues) and understand card mod support is not provided in this repository.

Current Behavior

Hi everyone,

I’m facing a strange issue after updating to the latest version (Core 2026.4.1, Frontend 20260325.6). Some icons in mushroom-chips-card are completely invisible on PC browsers, while they work perfectly on the mobile app.

The Issue:
On the same line, some icons disappear while others are visible:

Occupancy Chip: No icon is displayed, but the Alarm Chip right next to it shows its icon perfectly.

Doors/Windows Chips: No icons displayed, but the Lights Chip on the same line works fine.

What I've tried (Desktop PC):

Tested on Edge, Firefox, and Chrome (all show the same bug).

Cleared browser cache and performed a Hard Reload (Ctrl+F5).

Forced "Reload Resources" in Dashboards.

Crucial Test: The ONLY way it works on PC is using a simple type: entity chip with a static icon. If I use type: template with logic (if/else), the icon becomes invisible on the PC.

Has anyone experienced this specific rendering bug on desktop browsers recently? Any help would be appreciated!
