marginBottom has not effect in the header

[Kembreg1405]

Describe the bug and add attachments

We created a section.
We created a header.
There is no space left below the header.
Either we are doing something wrong or the 'marginBottom' in the section has no effect.

Expected behavior

Space should be left below the section header.

Steps to reproduce

$Margin['marginBottom']=2000;
$section=$phpWord->addSection($Margin);
$theheader=$section->addHeader();
