title: Highchart legend overlapping when change window size
body: <p>Automatically legend title has style <code>text-overflow: ellipsis;</code>, but I need to show all text from legend title. So, I need to set <code>text-overflow: clip;</code>.
  When user change window size, legend items overlapping each other or<br>
  move to outside of chart container.</p>
  
  <p>You can reproduce it here: <a href="https://jsfiddle.net/6ybv9kjx/6/" rel="nofollow noreferrer">https://jsfiddle.net/6ybv9kjx/6/</a>
  For reproduce you should change window size, when chart initialized.</p>
  
  <p>Also, legend items showing be a certain rule. If all text in legend item doesn't placed in one line with previous item, item move to next line. I need, that legend item can breaking words. Is it possible?</p>
