integration_entities('browser_mod') showing unexpected behavior

[Dtrotmw]

My Home Assistant version: Core 2025.1.0
Supervisor 2024.12.3
Operating System 14.1
Frontend 20250103.0

What I am doing: I'm trying to list all the browser_id's belonging to this integration

What I expected to happen: a list of entities

What happened instead: It varies; it produces a null result immediately after a system reset then is populated each time a new browser logs on

Minimal steps to reproduce:

integration_entities('browser_mod')

Error messages from the browser console: no error messages, but function returns null

By replacing the space in the checkboxes ([ ]) with an X below, I indicate that I:

• [ X] Understand that this is a channel for reporting bugs, not a support forum (https://community.home-assistant.io/).

• [ X] Have made sure I am using the latest version of the plugin.

• [ X] Have followed the troubleshooting steps of the "Common Problems" section of https://github.com/thomasloven/hass-config/wiki/Lovelace-Plugins.

• [ X] Understand that leaving one or more boxes unticked or failure to follow the template above may increase the time required to handle my bug-report, or cause it to be closed without further action.

I should add that it behaves differently in developer tools than in a sensor. In developer tools the list of sensors grows each time a browser_mod entity gets updated whereas the same YAML in configuration.yaml defining a sensor periodically gets stuck, at least until the template yaml is reloaded.
