Description

When I work with Symfony web application (PHP framework) I usually have to edit larger YAML files. In the last releases Netbeans really slows down when editing those files. After some small changes in the file the loading indicator is displayed and everything gets extremely slow.

This is why I still have to use Netbeans 8.2 which lacks some nice features (e.g. conditional breakpoints in PHP Debugger).

I'll attach an example YAML file which makes my IDE unresponsive. I hope you can reproduce this issue.

Other file types like large PHP files are not affected.
