[html] Format onPaste issues with HTML

[HunterMitchell]

• VSCode Version: Code 1.9.1 (f9d0c68, 2017-02-09T00:26:45.394Z)
• OS Version: Windows_NT ia32 10.0.14393

Steps to Reproduce:

1. Create an HTML document like below
   

2. Copy the nested-content div
   

3. Since we copied the spacing on the left (along with the text), we should be able to place our cursor to the very left and paste (or even just paste). Instead of the correct formatting we get something like this:
   

   or this (without moving the text cursor)
   

I assume this is an issue with the newer format feature, but I could be wrong.

I'm not sure this should go there but one nice thing I noticed about Java IDE is the fact that when pasting text inside a string, the pasted string is escaped if necessary.

So, pasting I'm doing well here:

let message = 'paste here: ';

would result in:

let message = 'paste here: I\'m doing well';

I have an issue with formatOnPaste:
copy the following code into <script></script> with "editor.formatOnPaste": true, it looks not good
(function() {
var updateButton = document.getElementById('updateDetails');
var cancelButton = document.getElementById('cancel');
var favDialog = document.getElementById('favDialog');

// Update button opens a modal dialog
updateButton.addEventListener('click', function() {
favDialog.showModal();
});

// Form cancel button closes the dialog box
cancelButton.addEventListener('click', function() {
favDialog.close();
});
})();
