eMail Renders after a long pause

When I’m reading eMail, it’s typical that most of the page renders immediately, but then there’s this huge pause while some pieces have to be updated from the sender’s website. It would be preferable if the part of the eMail that’s available is shown rather than flashing up on the screen, then blanked out until the rest is available. Very annoying. Thank you!

It is already fixed in the version 5.
