This doesn't happen for me. Which version of macOS is this? Does it reproduce with Safari Technology Preview?

macOS version 10.14.5 This doesn't happen on Safari Technology Preview. I made sure all the same extensions are turned on in Safari Technology Preview as in Safari and Tech Preview doesn't have the freeze. The freeze is very apparent in Safari.

Just tested Safari with all extensions turned off in Safari. The freeze happens all the time. If any text field is focused in and you press cmd + t or cmd + w to either open or close a tab, the action is not instant.

This indicates that the issue will be fixed in a future version of Safari since Safari Technology Preview doesn't reproduce.
