I'll investigate this when I find the time.
It's a pity you removed too much from the IssueSubmissionTemplate, thus destroying the purpose of the template.

Footers are bottom-aligned. SpaceBefore makes no sense for the first paragraph of the footer.
However, it seems that SpaceBefore is not handled correctly for the first paragraph of a footer. While SpaceBefore should be ignored completely for the first paragraph of the footer, it is possibly included when calculating the height of the footer, thus resulting in space after the footer, not before it.
