Thanks, mwmoskwa, for your helpful suggestions. I have been fairly careful to let pages fully load, but that does not always work. A bigger problem in all cases is that the tools give you know warning when they truncate a web clipping, so you have to waste time revisiting the site and manually copy/pasting the same thing again--a big pain in the you-know-what! 😉
The Android version of the clipping tool is worse because it seems to get "jammed" at times on "full page" pixels, not text mode. You have no choice about it, even if the article is a traditional text page (again, even in a significant and respectable publication).
Regardless, in these days a bad web clipping tool means a bad note-taking tool. OneNote really has to up its game in this matter. They should be testing across numerous types of sites including extremely long newspaper and magazine articles, etc. There should be feedback on possible issues and alternative choices presented when there are problems, etc., don't you agree?
Have a great day.
