It seems as though the content_script only runs once on each page
load. It's not continuously sending the selected txt to the background

For example, the below content_script reveals that the only way to

before a page finishes loading.
chrome.extension.sendRequest(window.getSelection().toString());
console.log(window.getSelection().toString());
