If I see a gap between two lines of text, and that gap vanishes when I commit the document to the web or save it to a file, then it’s not ‘WYSIWYG’. But this has been my experience with 100% of such editors.
I propose a new acronym to replace ‘wizzy-wig’:
WYSMBWYGIYLBIACWBFRTWNBMCTYSSIYUC
What You See Might Be What You Get if You’re Lucky but it Almost Certainly Won’t Be For Reasons That Will Never Be Made Clear to You So Suck it Ya Ugly Cunt
Not as pithy, but at least it’s accurate.
Hah, just a quick search for the image, but the point is that your average word processor is WYSIWYG – so much so that the phrase has fallen out of fashion, because any other concept (e.g. a TeX client like LaTeX) is foreign to your typical user. You edit the formatted document directly, and it’ll always look the same on screen and print as it did at the point of edit.
Granted you can enable alternate views in MS Word, like draft layout or web layout, but they’re not the default.
The one caveat is that documents made in the Word Desktop app can look different if opened in O365
