Robin Ward 4f328089d6 FIX: Force timeline/progress to re-insert into DOM on topic change
We have CSS animations which depend on the timeline/progress being
completely cleared when navigating from one topic directly to another.
This always worked because our loading component would clear the entire page
between topics but with our new experimental loading component the DOM was being
re-used.

This patch ensures that the timeline is removed completely from the DOM
if the topic changes.
