title: JQuery UI Tabs Not Displaying Correctly - Internet Explorer
body: <p>I'm trying to get started with Jquery UI tabs and I'm running into an issue with the demo they have on their site. It runs fine for me on the site itself, but when I download the source and all the other files to run it on my machine, it initially renders correctly like this:
  <img src="https://i.stack.imgur.com/KKRvL.png" alt="Correct Tabs behavior">
  but when i click on any of the other tabs, they render like this: 
  <img src="https://i.stack.imgur.com/ZyTDT.png" alt="Incorrect Tabs behavior"></p>
  
  <p>Clicking the leftmost tab always makes things look correct, but clicking the other tabs cause the lines I have circled not to be rendered. It works fine for me in Firefox and Chrome.
  Has anyone else seen something like this before?</p>
  
  <p>I'd be really grateful for some advice.</p>
  
  <p>Thanks,<br>
