Reg test diffs for XML - noise in all tests

[James Lowe]

Hello,

Since a few days ago I am now nearly always getting two or four reg test 
diffs show, albeit just for cell counts, for XML tests.

See example attached.

It's not stopping me doing anything but it does add noise and I 
wondered, as there are no image diffs ever for XML tests, if this is 
pointing to something more serious or potentially problematic?

Regards

James
