nukeBloggerClickTrap.js

// what substring in the URL indicates to us that we are editing the blog post
let isPostPreview = 'post-preview'
// the query selector to use for referencing the click trap element 
let querySelectorForClickTrap = '.blogger-clickTrap'
// how long should the delay be before we attempt to remove the click trap element 
let wait = 3000
if (window.location.href.indexOf(isPostPreview) !== -1) {
  setTimeout(() => {
    console.log('nukeClickTrap')
    let it = document.querySelector(querySelectorForClickTrap)
    if (it) {
      it.remove()
      console.log('removed')
    } else {
      console.log('not removed')
    }
  }, wait)
