should we also hide the .page-description element above while this.loadMoreTask.isRunning && this.sortedVersions.count === 0?

So, this is regarding the initial load (like the 'is-empty' check mentioned above)? I presume this could be achieved via

style="{{unless this.sortedVersions 'visibility:hidden'}}"

(which could also be implemented using a CSS class and style).

I don't really have a preference on this, but I think the reasoning behind it is to make it more noticeable that it's still loading and is an initial load. So, I'm okay with this.

I'm also wondering if we should prevent the page loading progress (the yellow one at the top) from completing until the first versions have finished loading.
