PartDesign: Ensure the suggested Body is visible when creating a Sketch.

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Problem description

I am creating a new Sketch attached to the face of a Non-Active Body.

A pop-up appears asking me which body I want. This is correct and good.
FC also suggests preselecting the right object (the one that had the face selected). This is correct and good.

However, it does not scroll the list to that selection. This is a poor thing, because the user does not know that something is already selected. The list should scroll at the selected object position, so the user will see the selected element and, most of the time, just hit Ok. If the list does not focus on that selected element, it is kind of useless.

See this example, if there is something selected, I don't know until I have to scroll that list to see. Then the point of having a suggested body is useless.
