Ok, I was just checking the support forum for exactly the same reason.
I have found that there are breaks put in the page that are not in the post page – I have tried to remove all characters after the text and then go directly into the tabs and still the huge space occurs. some are larger than other – this one is bigger than expected – but not as big as some –

It would be nice to know what is going on – and where the unexpected breaks are coming from..
