Released: October 2, 2017 Version 1708 (Build8431.2094)
Part of the release notes mention:
'Fix an issue where the pattern style of a cell doesn’t render correctly after adding a header or footer in Page Layout view.'
I am about to install and test.
EDIT: the Office 2016 Deployment Tool is still downloading Version 16.0.8431.2079. I will try again later today or tomorrow.
UPDATE 2:16.0.8431.2094 is now downloading via the Office 2016 Deployment Tool. Interesting note is that the date on the release is Oct. 4th, not the 2nd like it was previously.
UPDATE 3: The cells don't turn black anymore in Page View when there is a header/footer. Thanks MS for fixing the bug.
