Bootstrap dropdown-toggle flashing error

Question

I'm working on a preassembled file that has a dropdown in the navigation bar. The client wants the dropdown to open on mouseover. So I added in some jQuery to add the class 'open' (as bootstrap does when the dropdown is clicked).

This worked but has caused a new issue. When clicking one of the choices in the drop down, the drop down now flashes once before closing and taking me on to the bage of my choice.

I have researched this and can not find out what is causing this 'flash'. This was the only article I found that showed promise: Twitter bootstrap stop propagation on dropdown open

Any help would be GREAT!

I tried to recreate this issues in this JSFiddle, but I do not get the 'flash'.

Here is my HTML code...

<div class="navbar navbar-default" role="navigation">
  <div class="container-fluid ">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="STUFF.cfm?page=home">
        STUFF AND MORE STUFF
      </a>
    </div>
    <div class="navbar-collapse collapse">
      <ul class="nav navbar-nav navbar-right">
          <li class="dropdown">
            <a href="##" class="dropdown-toggle" data-toggle="dropdown" id="nav-dropdown-toggle">FULL NAME STUFF <span class="caret"></span></a>
            <ul class="dropdown-menu dropdown-menu-css" role="menu">
              <li><a href="STUFF.cfm?page=home">Home Page</a></li>
              <li><a href="STUFF.cfm?page=home">STUFF 1</a></li>
              <li><a href="STUFF.cfm?page=home">STUFF 2</a></li>
              <li><a href="STUFF.cfm?page=home">STUFF 3</a></li>
              <li><a href="STUFF.cfm?page=home">STUFF 4</a></li>            
              <li class="divider"></li>
              <li><a id="logout-li" href="##" name="btn-logout">Logout</a></li>
          </ul>
          </li>
      </ul>
    </div>	<!--/.nav-collapse -->
  </div>	<!--/.container-fluid -->
</div>

Here is the JS

(function(){
  
  $("ul.nav.navbar-nav.navbar-right").hover( function(){

    $("li.dropdown").toggleClass('open');
  })
})()

It should be noted that our base language is ColdFusion. Thank you all!

Answer 1

My script was toggling the class 'open' too often, thus causing a 'flashing' effect. Instead I rewrote my JS as follows checking first if the 'open' class was already present:

    $("ul.nav.navbar-nav.navbar-right").mouseenter(function(){
      if(!$("li.dropdown").hasClass("open")){
          $("li.dropdown").toggleClass('open');
        }
      })
      .mouseleave(function(){
        if($("li.dropdown").hasClass("open")){
            $("li.dropdown").toggleClass('open');
          }
        })
