If you expand and collapse a PickList, then expand a different one, the first one briefly re-expands

[mtkennerly]

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

• If you expand PickList 1, do not collapse it, and then expand PickList 2, it transitions smoothly.
• If you expand PickList 1, collapse it, and then expand PickList 2, the issue occurs. PickList 1 will re-expand briefly before PickList 2 expands.

To reproduce this, run the pick_list example with these changes (relative to commit 23299a5):

         ]
         .width(Length::Fill)

What is the expected behavior?

After collapsing PickList 1, it should not re-expand before PickList 2 expands.

Do you have any log output?

This is similar/related to #1484, but that one is about mismatched options (PickList 2's options appear in PickList 1's overlay just before PickList 1 collapses), whereas this ticket is about PickList 1's overlay reappearing.
