Scrolling in report is broken (frappe-table)

Scrolling with the mouse scroll button stops working after a couple of pages scrolled.
If you move the mouse cursor, it starts working again. but then stops until we move the cursor again.

You can see the same problem with keyboard scrolling: click on a cell and hold the down arrow key, it will starts scrolling but then stops after a couple a pages scrolled.

Same problem if instead of holding down arrow you press down arrow (or page-down key) multiple times.

I cannot be the only one utterly bothered by this buggy behavior ?
Anyone experience the same issue ?

I can reproduce the behavior in the frappe-table demo page:
