My material editor doesn't show any node previews

I’m trying to follow this tutorial
However, my material editor doesn’t show any node previews (for example the Linear gradient passed in the Sine), which makes it hard to see if what I’m doing works. I’ve enabled Live Preview, Live Nodes, Live Update, but still no dice. Any idea why this is happening?

Wow, I did not expect to encounter an actual bug so close to the interface!

As a quick workaround, I’ve managed to get my previews working by right clicking my last node and clicking in order “Start Previewing Node” > “Enable Realtime Preview” > “Stop Previewing Node”. Any other sequence will simply not work.
EDIT: I forgot to say this will start previewing all nodes connected to it, provided they have realtime preview enabled.

This works.
