Some things that are considered "node attributes" can be quite long:
- External link URLs
- Template parameters
The diff shows all attribute changes as remove/insert which can be quite hard to read, and take up a lot of lines in the sidebar, e.g. https://en.wikipedia.org/w/index.php?title=Eight_Legged_Freaks&curid=956388&diff=1000619828&oldid=1000322446&diffmode=visual
We could run a linear diff on attribute changes to make this shorter and more legible.
