Check if selection is a link

selection.js

const selection = getSelection();

const isALink = selection.type.toLowerCase() == "range") &&                  // Selection is a range, and
        selection.anchorNode == selection.focusNode &&                      // Starts & finishes in the same node, and
        selection.anchorOffset == 0 &&                                      // Starts at beginning of the node, and
        selection.focusOffset == selection.focusNode.textContent.length &&  // Finishes at end of the node, and
        (selection.anchorNode.nodeName.toLowerCase() == 'a' ||              // Node is of type 'a' (link/anchor), or
         selection.anchorNode.parentElement.nodeName.toLowerCase() == 'a')  // Node parent is of type 'a' (link/anchor)
   

// Do not convert, or show actions if selection is a link (usually when user has right clicked on a link)
