[Bug]: Custom layout size for cards no longer working

[S-360]

Requirements

• I checked the troubleshooting section in the README to verify that I have the latest Mushroom version.
• I did a search to see if there is a similar issue or if a pull request is open.
• I have read the state of card mod support (in pin issues) and understand card mod support is not provided in this repository.

Current Behavior

In the layout section of a card changing the row via yaml to a custom size no longer works. I have a number of Mushroom Entity cards with a layout of,
Columns: 4
rows: 0.8

and also a number of cards with,
Columns: 4
rows: 1.5

This no longer works and the cards seem to size only to whole numbers.

This doesn't seem to effect the template mushroom card. Have not tested on other cards.

Expected Behavior

Expected custom card sizing to remain the same.

Resolved by downgrading to version 4.0.8

Steps To Reproduce

upgrade to version 4.1.0 and 4.1.1

Context
