RegExp is crashing the process #349

try the following line of code in the browser or node through terminal (is going to hang the process)
is not crashing firefox though..

'<input type="email" name="email" class="form-control" ng-model="user.email" required'.match(/^<([\w:-]+)((?:\s*[\w:.-]+(?:\s*(?:(?:=))\s*(?:(?:"[^"]*")|(?:'[^']*')|[^>\s]+))?)*)\s*(\/?)>/)

is not actually crashing the process but takes a veeery long time to return and adding more attributes to the html is even worst. Related to #213

this regexp is returned by startTagForHandler and the string is actually part of the html that is going through the parser.

apparently for what I googled, is a bug in the js engine http://stackoverflow.com/questions/12825950/why-does-this-javascript-match-function-crash-my-browser
