Javascript for Keyboard Shortcuts - No scroll issue

We have been using this javascript to pop up a keyboard shortcuts layer. (Tied to a player option)

// create a new keyboard event
var event = new KeyboardEvent('keydown', {
key: '?',
shiftKey: true
});
// dispatch the shift+? key press event
document.dispatchEvent(event);

Starting with publishes done with the Feburary Storyline update, the user is unable to scroll through the shortcut list 

This happens in Articulate Review, SCORM and Web publishing. It happens on Chrome, Edge and Firefox.

When reverting to the Jan 29 update, the functionality is restored.
