title: Codemirror last line of textarea is unreadable and half cut off
body: <p>I am using CodeMirror <a href="https://codemirror.net/" rel="nofollow noreferrer">https://codemirror.net/</a> to turn a textarea into editable code. </p>
  
  <p>CodeMirror handles the resizing of the textarea, and it mostly works. But the last line of the text in the text area is half-cutoff.</p>

  <p>This problem does not happen when the codemirror CSS is allowed to operate alone, but when combining it with bootstrap css (et al), we get this problem. </p>
  
  <p>Codemirror has lots of inscrutable options, and I am pretty sure one of them fixes this problem. Alternatively, it would be helpful to know which css style parameter or html parameter I should be fiddling with. </p>
  
  <p>Where should I start solving this problem?</p>
