UPDATE : Qaru has released PageDown , which fixes all of the above errors. Use this instead. Original answer below ...
Technically, the WMD version of Google Code is official, supported by some of the SO employees (view the source to access the actual code). However, he still suffers from the error described above. In fact, this does not match the current version of SO in many ways.
Yang's answer really works, but I took a look at what Stack Overflow actually does, de-minimizing their addBlankLines function. They add the following code to the specified function between lines 1498 and 1500:
if (navigator.userAgent.match(/Chrome/)) { "X".match(/()./); }
I canβt understand what this code actually does, but it works! And this is what Qaru uses right now, so it can't be too bad :)
