How to reproduce:
1. Open the attached project (case-1265256.zip)
2. Enter Play Mode
3. In the Game view click on the Dropdown displaying 'Option A'
4. Select the Dropdown value 'Option B'
5. Before the Dropdown closes and becomes not interactable quickly select 'Option A'

Expected result: after selecting 'Option B' the Dropdown immediately becomes not interactable
Actual result: it is still possible to select another value before the Dropdown becomes not interactable

Reproducible with: 2018.4.26f1, 2019.4.6f1, 2020.1.0f1, 2020.2.0a19

Notes:
Dropdown.onValueChanged is called twice when the issue occurs

    Resolution Note:

    Setting the dropdown.interactable = false is different then setting each button in the dropdown to false. The issue here is that the dropdown comprises of multiple elements (buttons) that are still interactable. To fix this you would need to point each dropdown element to each other dropdown element so when its pressed it sets those to not interactable.
