Demonstration of the freeze

Safari freezes for 2-3 seconds (sometimes more) when closing tab with text input in focus. Text input being any text field where you have to type. For example Twitter search bar or GitHub search bar.

This freeze doesn't happen if you do it when no text input field is selected. The tab closes instantly as it should.
