Menu Items Cannot Be Scrolled To

I've implemented the menu control in a sidebar within my application. It's worked like a charm until a couple of days ago. Now, the menu loads correctly but sub items go away when I try to mouse over them.

Hi lance, 
Thank you for contacting Syncfusion support. 
We have checked the reported issue with our latest version (v16.4.46) by rendering the EJ2 – Menu (vertical orientation) inside the Sidebar and the sub menu items are shown properly on mouse hover in  
our end. For your convenience, we have attached the demonstrated sample and hosted a live demo. 
Hosted sample:

Could you please check again once cleaned the browser cache and get back to us? If still issue persists, we would like to know the following details. 
1. Please share your Essential Studio product version that you are currently using. 
2. Could you please ensure that the assemblies and assets (CSS & scripts) references are referred from same product version
3. Please share the code snippet or the details if you did any customization with Menu or Sidebar. If possible, please replicate your issue with the above sample and get back to us.

I have cleared my cache and verified that everything is within the same version. As I said, this is a new issue that has arisen over the last few days. To my knowledge, nothing has changed with the project setup in that time. I'm attaching my layouts view and menu view. Layouts loads menu as a partial view. The object that is used for menu items is defined below.

public class JsonMenuItem
            public int Id { get; set; }
            public int ParentId { get; set; }
            public string DisplayName { get; set; }
            public string URL { get; set; }
            public int DisplayOrder { get; set; }
            public bool Active { get; set; }

I'm unable to replicate it in the given solution; however, the problem does persist in my solution.
