This happens to me frequently when I use the insert HTML option in the
VEC. I do not know why it happens.But, when I notice it, I quickly
switch to adding the content via script like this, wrapping my updated
element/content in a parent element with its own ID...var newcontent = `
New content here
`; if (document.querySelectorAll('temp_tt').length < 1) {
document.querySelector('#actualcontentelement').innerHTML += newcontent;
}
