DragValue with min_decimals set to 1 formats 0.0 as 0

[Skgland]

Describe the bug
With min_decimals set to one all values should be displayed with at least one decimal,
but 0 is displayed instead of 0.0

To Reproduce
Create a UI containing a DragValue with min_decimals set to 1 and with a current value of 0.0.
e.g.
ui.add(egui::DragValue::new(&mut 0.0).min_decimals(1))

Expected behavior
min_decimals is honored and 0.0 is displayed.

Additional context

This is probably due to this special case:

It looks like this special case was added in ebc2486#diff-3878bfa9f60333dd78982f3697643c6755ff8378f18b54fff03973c1eff5fcc8L159-R173 more than 3 years ago, and kept this way ever since. But I don't know what is the reasoning behind it.
