Description
The Selection api anchorOffset and focusOffset docs are hugely misleading and data on this matter is very scarce. I clarified what those offset return in the case of a non texty node in anchorNode or focusNode
Motivation
A custom project I am working on heavily reliant on selection api. The docs on this matter are scarce and there are a lot of caveats not mentioned anywhere or in very obscure parts of programming forums. This specificly came up from testing my project and this SO issue which also mentions fixing MDN docs but i guessed there was a regression from 2013 to today.
