<p>
The <code>scrollbox--with-header</code> pattern offsets the top
scroll-hinting shadow to accommodate one header-like element with a
touch-target height (currently 44px).

I wonder if having a .hyp-u-layout-table-header would help.

It could also include min-height: $touch-target-size.

Good idea! Tell you what. I was thinking of implementing a simple Scrollbox container component in my next body of work. I will look into introducing a pattern that corresponds to "a header of the correct size to put in a scrollbox" along the lines of what you're suggesting here. 👍🏻
