#3033 bug fix

Thanks for working on this issue.
We have another possible solution for this problem (making the component uncontrolled), but I am not 100% certain that it is solving the issue you are having.

To make the commit easier to review, would you do the following three changes:

• run yarn prettier on this commit so the formatting is consistent with our established code style. This will make the diff smaller (few lines have unnecessary spaces) and easier to read
• make sure the tests pass (currently Flow is complaining about missing props)
• Add few lines to the commit message explaining what the issue you encounter is, and why your changes fix it.
