title: Using a regex within Sublime Text results in running out of stack space error
body: <p>Within sublime text I'm trying to match a <strong>single</strong> double quote followed by the html tag <code>&lt;br&gt;</code>.  Any string can come after the html tag and the double quote must not be preceded by a double quote.</p>
  
  <p>I've gotten as far as having my regex meet my expectations when testing in <a href="https://regex101.com/r/HHNB1E/4" rel="nofollow noreferrer">https://regex101.com/r/HHNB1E/4</a>.</p>
  
  <p>This is my regex: <code>^((?!").)*{"&lt;br&gt;}.*$</code>.</p>
  
  <p>However, when I put this into Sublime Text it throws the error "Ran out of stack space trying to match the regular expression".  I'm assuming my regex is inefficient given I am not very experienced with them.</p>
  
  <p>Example results expected:</p>
  
  <p><code>foobar""&lt;br&gt;</code> - No match</p>
  
  <p><code>foobar"&lt;br&gt;</code> - Match</p>
  
  <p><code>""&lt;br&gt;baz</code> - No match</p>
  
  <p><code>"&lt;br&gt;baz</code> - Match</p>
  
  <p><code>foo&lt;br&gt;baz</code> - No Match</p>
  
  <p>Do I need to improve the regex for efficiency or am I doing it completely wrong?</p>
