Describe the issue you are experiencing

After the most recent update, the graphs in my history view are not connecting cleanly anymore. I can confirm that the data has been available the whole time.

Describe the behavior you expected

I expect to see continuous lines for the continuous data. This started breaking once I updated.

Steps to reproduce the issue

1. I'm tracking my solar production and consumption via enphase's integration.
2. Over the course of the day, it randomly doesn't appear to log data.

What version of Home Assistant Core has the issue?

If there are gaps in the graph that likely means the sensor is going temporarily unavailable or unknown, which would be an issue with the integration, not with frontend.
