[BUG]Vertical Size doesn't match grid

[guidog66]

The card is slighty taller than other cards with the same vertical grid size, making arranging a dashboard with this card very difficult.

As can be seen in the screenshot, on the lower edge of the card: the lowest line is what will be visible after editing, the upper line is what the card should be and is only visible during editing

HA version 2025.8.3

Similar vertical size issue - I have set the vertical grid size to 6, but it will not stretch beyond 5.
