I am not sure if the issue was not mentioned in the list of related bugs that was presented to me before entering this text. It could be I have not enough technical knowledge to spot that it was mentioned.

The related URL is https://www.digitalocean.com/community/tutorials/how-to-set-up-dnssec-on-an-nsd-nameserver-on-ubuntu-14-04. I could not spot other lines of the URL that are missing in the reader view page, other then the lines I mentioned below. I believe there are not other missing lines. The section that I have spotted the missing lines in seem to be different then the other sections of the article. It could be the difference is the key for the missing lines.
The attached 2 pictures are from the last few lines of the article. I will probably upload 1 of the 2 separately from submitting this this text, because I can not see a way to upload 2 pictures at once. By comparing those 2 pictures, the problem seem to me obvious. What I think is the key difference from the other parts of the article is the copy button, at the top right corner of the non reader view display.
The lines that constitutes the #!/bin/bash script were not displayed in reader view.
