"Fetch more toots" now frequently appears above toot UI buttons of last toot in timeline

Issue

Lately the "fetch more toots" link has been appearing within the last toot in the timeline (above the boost/etc buttons) rather than below it.

Also, it would be good for "fetch more toots" to be more visually distinguishable from the background, especially with the support of markdown etc from Pleroma.

Steps for reproducing the issue

1. Scroll to the bottom of the timeline.
2. Often, "fetch more toots" will display in the wrong location.
