FilterTextboxWidth is not always in px

[negberts]

Describe the bug
In the documentation it says the FilterTextBoxWidth is always in px.

However, if the grid as vh as unit type, the textbox width is also measured as vh

To Reproduce
Steps to reproduce the behavior:
Create a grid with unit type Vh

<Grid @ref="grid"
      Unit="Unit.Vh"
      Height="80"

Add FilterTextBoxWidth="50" to a Column.

The resulting HTML:

<input class="form-control" style="width:50vh;" type="number">

Expected behavior
FilterTextBoxWidth is always in PX as the documentation describes
