Header doesn't scroll

[hhoek]

Header doesn't scroll (Edge browser).

This one is pretty hard to solve as the header and the table itself are not associated/connected: they are technically part of a different thing. The easiest way to solve this within the current constraints is to make the UI wider of split the results into different tabs.

To prevent confusion on what metric belongs to what column, a popup is added to each metric so you can see what the result is about when the scrolling is off (like in the screenshot).
