--- Comment #2 from Deepak Aravind <codesculptures at gmail.com> ---
The shouldSelfClose and elementCannotHaveEndTag were contradicting each other where i believe both return opposite values but as per current implementation  producing same result

const myImg = document.createElement("img")
const childDiv = document.createElement("div")
img.appendChild(childDiv)


Consider current, targetNode = myImg
>From the above case, 
shouldSelfClose returns false as it has child(s)
elementCannotHaveEndTag returns also false as it would always return false for void-elements



We have to make a decision clearly here,
1.Allow children in void elements (as per spec, it is incorrect, but chrome doing this)

2.shouldSelfClose would give priority for whether it is a void element immediately return true over hasChildNodes

3.Don't allow (or Ignore) appending node on void elements
