The toolbar flashes when navigating back from navigation controller

[ldakhoa]

Describe the bug
The toolbar flashes when navigating back when navigating to the next screen, then goes back with the keyboard showing up

To Reproduce

Focus on any field with a toolbar enabled, navigate to the next screen using navigationController.pushViewController, then swipe back and press the back button. Then you will see the toolbar flash for a second.

Note that we navigate from the search screen, to keep a better user experience, we want to keep the keyboard show, so we cannot use endEditing to fix the issue

Expected behavior
The toolbar not flashing anymore
