Hline (hlines option) protrudes

I am sorry if this issue was previously discussed.

As shown in the snapshot below, horizontal line is extended to come up to the horseshoe (both sides). This snapshot was taken from the dashboard.


Strangely, the line does not protrude in the editing dialog of the card (see below).


Here is the YAML setting;
```yaml
`type: custom:flex-horseshoe-card

- entity: sensor.thi_living
decimals: 0
name: Living
area: Living
- entity: sensor.living_sensor

This is not a serious issue, but I will be happy if you fix this.
