@netochaves Could you add a failing test case? This should help to prevent similar regressions in the future.

[netochaves]

@oliviertassinari Sure! It will fail if the popover prop open is false, do you know another case?

[oliviertassinari]

Great! I have updated the test case to be failing without the fix. I think that we are good to go 🚢.

@netochaves Thanks!
