Describe the issue you are experiencing

When using the Portuguese (BR) language and displaying entities that contain numerical values with decimal points (such as temperature sensors, percentages, and energy consumption), these data are not displayed correctly or do not appear at all.

This behavior causes slowness, crashes, and failure to render cards in dashboards or when viewing devices in the configuration menu, making the app unusable. Regardless of the chosen number format, the issue persists, but changing the language to English resolves it. This happens in the Home Assistant app or in any browser on iOS (tested on iOS 15.1, but there are reports of other affected versions).

Describe the behavior you expected

Numeric values with decimal points should be displayed normally without causing slowness, crashes, or rendering failures in the dashboard cards in the Portuguese BR language

Steps to reproduce the issue

Change the display language to Portuguese (BR).
Navigate to a card in the dashboard or the configuration menu where decimal numbers are displayed (e.g., temperature, percentage, etc.).
Refresh the page by scrolling down
Verify if the card or entity is not displayed correctly, if the app becomes slow, and in some cases, depending on the number of entities with decimal values, if the app crashes.
