Issue description:
With minimal size grid view show only one element, but when I resize it by one pixel, then dock show two elements in row.

This is expected. What is the problem here ?

[qarmin]

I think it will be better if it will display in at least two columns, especially if this dock only needs to increase the minimum width of this element by only 1/2 pixels.

With one column it looks quite strange.

I would simply reduce the minimum width.
