Horizon theme bug: Category heading container sticky in topic lists

So what is the way forwards for this?

I do wonder if we should simply hide the category description on mobile for Horizon. It is kind of doubling up information anyway, in a space that is very tight.

I’ve achieved this with some simple CSS in the Mobile tab of a TC:

.category-heading.--has-logo {
    display: none;
}

Perhaps this should be included in Horizon?
