Vertical scrollbar is not always visible when the columns overflow the container horizontally

[gmartinezig]

I have to scroll all the way to the right to start seeing the vertical scrollbar:

Expected behavior:
When the rows exceed the vertical space, the vertical scrollbar should be always visible.

That's a bit of side effect of the virtualization being on the rows, so the horizontal scroll is the native browser handling and that's scrolling the entire grid pretty much, thus the scroll bar sitting at the end. I don't know if the lit virtualizer has an option for a separated scroll handler (kinda doubt it) that we can place elsewhere. Otherwise, it'd be down to if it's at all possible to restructure the scroll containers to have the scrolls in the same container.
