Issue Summary

When the Draft Warning message is discarded, the Undo and Redo buttons appear active (black), and nothing happens when clicked. In version 8.5.12 of Confluence, when the Discard link is clicked, both the undo and redo buttons instantly turn gray (inactive).

Steps to Reproduce

1. 1. Collaborative Editing is OFF.
   2. Put the page in Edit mode.
   3. Make some changes to the page so that the undo button turns black, but do not save the page.
   4. Click the Close button.
   5. Put the page back in Edit mode.
   6. In the "draft warning" pop-up, click "discard it."
   7. Note that the undo and/or redo buttons are black instead of gray.

As soon as you click somewhere on the page, the undo/redo buttons revert to gray as they should be.

Expected Results

Undo and Redo buttons should appear gray (inactive).

Actual Results

Undo and Redo buttons appear black (active).

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
