DW - fixed in alpha.2

If I understand the original bug correctly, I am still having this issue on alpha.2.

To elaborate on what I'm experiencing, the "live card preview" to the right of the code editing area does not update at all, until the changes are saved and the editor is re-opened. All my other cards have previews that update with any change to the content, so I feel confident this is specific to tabbed-card.

I am using the same code example as the original reporter. For comparison, creating a new weather-forecast card that does not use tabbed-card will show updates from the code editor immediately. For example, changing show_forecast from true to false will cause the card preview to update in real time.

Environment:

- OS: Windows 10
- Browser: Chrome 126.0.6478.128
- Home Assistant Version: 2024.7.3
- Tabbed Card Version: 0.4.0-alpha.2

Thank you!

Edit: I should clarify that this happens with any child cards, not just weather-forecast.
