Grid item heigth not the actual amount of pixels as described in the documentation

[SamGeens]

Software version (please complete the following information):

• Browser: chrome, firefox
• Vue Version: ^3.0.0
• vue-grid-layout Version: 3.0.0-beta1

Describe the bug The grid item height isn't the actual amount of pixels as discribed in the documentation. According to the documentation the grid item heigth should be:

h
type: Number
required: true
Says what is a initial height of the item.

The value is a number that is multiplied by rowHeight.

To Reproduce Steps to reproduce the behavior:

1. Go to CodeSandbox Template
2. Note that the row height is set to 30
3. Inspect the grid elements and note that the item height isn't correct.

*The item heigth is here 72px while the expected heigth is: 30 2 = 60**

*The item heigth is here 112px while the expected heigth is: 30 3 = 90**

*The item heigth is here 152px while the expected heigth is: 30 4 = 120**

Expected behavior I expect the item height to be the actual calcalution the documentation describes: The value is a number that is multiplied by rowHeight

Additional info I wanted to use the row height to calculate what the heigth of and grid element should be before adding it. Let's say I want to add a grid element for a picture I can calculate what the height of the picture should be depending on the grid width to preserve the aspect ratio. If I do such for example the width of a grid item is 100px and I cant to keep a 2x3 ratio the of the grid height should be 150px. But when I set a row height of 1px and a grid item height of 150 the actual height of the grid element is always a bit of like described in step 3.
