'E', 'M' shortcuts can not be turned off

Issue Summary

Single character key shortcuts exist and do not have at least one of these required options: the ability to turn off single character key shortcuts, the ability to remap to a non-singular key shortcut, OR are only active when the appropriate user interface component has focus.

Steps to Reproduce

1. Navigate to the desired confluence page.
2. In the header section, navigate to the confluence help link and activate the keyboard shortcut link option.
3. A modal will appear containing the keyboard shortcuts, uncheck the "Enable shortcuts" checkbox in the modal and close the modal.
4. Reload the page
5. In the main content area of the viewed page, try interacting with the page with a single character keyboard shortcut such as "E" and "M".

Actual Results

"E" and "M" shortcuts work while "Enable shortcuts" checkbox is unchecked after page reload.

Expected Results

"E" and "M" shortcuts do not work while "Enable shortcuts" checkbox is unchecked.

Workaround

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