ListView header scrolling

Expected / Desired Behavior / Question

When there are a lot of items and columns that can not be fitted into the default height and width of the "ListView" control, vertical and horizontal scrollbars should be displayed. Header should be sticky only for vertical scroller, while horizonal scroller should allow the users to scroll the columns together with the values. Should be similar to what SharePoint Online does.

Observed Behavior

Header remains sticky for both vertical and horizontal scrolls.
Tried using "className" and "listClassName" with no luck.

Configuration:

The output:

We have followed the issue #1065, but it doesn't explain what exactly we should do to achieve this.

Steps to Reproduce

Create a new SPFx webpart. Import the "ListView" control.
Set "stickyHeader" property to "True"
Create several ViewFields to exceed the width of the ListView.
Bind the control with sample data to exceed the default height of the ListView.
Use the vertical and horizontal scroll.

Is there a way to set the "stickyHeader" option, so that vertical scroller shows all the records, while the horizontal scroller allows the users to scroll horizontally to view all the field values with the header columns?

Thanks!

Start with the ListView control's stickyHeader option and reproduce the behavior using several ViewFields and enough sample data to require both scrollbars. Verify that vertical scrolling keeps the header visible while horizontal scrolling moves the header columns together with the field values.
