Product Version = NetBeans IDE 8.2 (Build 201609300101)
Operating System = Linux version 4.7.5-200.fc24.x86_64 running on amd64
Java; VM; Vendor = 1.8.0_101
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.101-b13

Reproducibility: Happens every time

STEPS:
  * I have the following indentation settings for all the languages:
      Expand Tabs to Spaces: yes
      Number of Spaces per indent: 2
      Tab Size: 2
    inherited by all the languages (PHP and Javascript included)
  * I'm in a PHP page with this javascript code (please consider also the number of spaces included):
    $(document).ready(function() {

      function displayError(errNo, errMsg, errScript, errLine) {
        
        if (errNo==="") return;
        
        // Make of the error message string..
        if (errMsg!=="" && errScript!=="" && errLine!=="") {
          etc.
  * At the end of the line "        if (errNo==="") return;", I press [Enter] and the cursor positions itself
    at the beginning of the new line just under the "if". 
  * When I past the following two lines of code (please consider also the number of spaces included):
        // First, hide all the current error messages
        clearErrors();
     the indentation of the first line is broken from 8 spaces to 16 spaces.
  * Same result in PHP code
  * Same result in NetBeans 8.1 

ACTUAL:
  the indentation of the first line of pasted code get broken to the sum of spaces between the existing and the pasted ones

EXPECTED:
  the indentation of the pasted code must adapt to the existing indentation
