title: spyder debugging stops at the first line
body: <p>this is my code</p>
  <pre><code>a= 1+10
  b =1+20
  c=1+5
  print(a)
  print ('hello')
  </code></pre>
  <p>I set breakpoints on line 3 and line 5. However, when i run Debug (Ctrl + F5) in a Spyder Console, it got stuck as shown below even after I updated my Spyder:</p>
  <pre><code>----&gt; 1 a= 1+10
        2 b =1+20
        3 c=1+5
        4 print(a)
        5 print ('hello')
  
  ipdb&gt;
  </code></pre>
