How to undo auto-formatted html wrapping in Visual Studio?

Question

I have been editing HTML file in Visual Studio. There were many li elements in it. All of them were formatted this way (no matter how long the text was):

    <li>ExampleExampleExampleExampleExampleExampleExampleExampleExampleExampleExampleExample</li>

But after sometime (I didn't notice when exactly) the code has ben auto-formatted by VS (or accidentaly by me?) and looks like this:

      <li>
           ExampleExampleExampleExampleExampleExampleExampleExample
           LineWrapped
      </li>

I wonder is there any way to go back to the previous format without wrapping and having everything in one line?
