Example input

I attached a bit of javascript code inside a <syntaxhighlight> tag. Enter it
into an edit window and hit preview (or save). Most of the code is missing in
output, especially the laaaarge array.
On http://qbnz.com/highlighter/php_highlighter.php this input works as
expected, so either GeSHi shipped with this extension should be updated or the
bug is elsewhere.

1.0.8.11 was only released yesterday.. Patch in https://gerrit.wikimedia.org/r/#/c/20665/

Testing locally with 1.0.8.10, it works fine. Upgrading to 1.0.8.11 it shows exactly the same

It is however replicable on mw.org see https://www.mediawiki.org/wiki/User:Reedy/bug39498

I've merged 1.0.8.11, so we'll see if the update fixes mw.org later on today..

Apparently this is still an issue. Must be something in how we interact with GeSHi...

Even though this was filed first, I'm going to mark it as a duplicate of bug 45669 as that bug describes the actual issue rather than just the symptoms.
