User Comments:
vriha: for issue #215733

vriha: I did nothing, only large HTML file was opened

jglick: Opened changelog.html from Jenkins sources and just started to move caret down (did not edit). IDE froze at ~200% CPU for quite a long time. Finally managed to close the file and IDE recovered.



Maximum slowness yet reported was 32529 ms, average is 23311
