Battery display does not follow hide_table_gap configuration

[cooperuser]

Describe the bug

When setting the hide_table_gap setting to true, all tables correctly hides their gaps except for the battery table.

To reproduce

1. Use a clear config file by way of --config=/dev/null
2. Enable flags --battery and --hide_table_gap
3. Observe both those flags working on their own, but not together.

See top right of screenshot.
