I had to tamper with the recorded screen-capture video file to make it fit into this website (originally it was a massive .mp4 file). Maybe that’s why it looks “fishy”.
Anyhow, I understand how indenting in relation to code-blocks work now.
The problem/bug (or whatever you wanna call it) is still there: the conflict between edit mode and preview mode for the second way I did it (in the gif).
Here’s a better version of the clip if the gif above is unclear.
