ListGrid setCellFormatter() doesn't apply to summary

[har28]

Hi all, I'm trying to format my floating point numbers to 2 decimal places in a ListGrid by using ListGrid.setCellFormatter(). It works well for the list grid rows, however the formatter doesn't seem to be applied to the summary row. Is there any additional steps that I should do? Thanks.

Just realised that this is happening only in development hosted mode. The compiled version works well, so it seems good for me.
