Undo Keyboard Shortcut Ctrl+z is not working when using external keyboard

Summary

In Windows, the "undo" keyboard shortcut is CTRL+Z. In the recent Cloud Confluence editor, the button to undo has been removed, requiring users to user the "undo" and "redo" shortcuts instead.
However, the CTRL+Z shortcut does not appear to be responding in Windows environments.

Environment

• Confluence Cloud with New Editor.
• Microsoft Windows OS
• External Keyboard

Steps to Reproduce

1. Create a page in Confluence.
2. Make changes on the page.
3. Type CTRL+Z which would normally remove the last change made.

Expected Results

Last change should be reverted.

Actual Results

There is no response to CTRL+Z and the last change is not removed.

Workaround

No current workaround to undo changes.
