When Separation color space with "name" set as None it is falling back to an "alternateSpace" (color space) instead.
From the Pdf specification:
A Separation color space is defined as follows:
[ /Separation name alternateSpace tintTransform ]
Observed:
The None value is ignored and the color space fallbacks to the Lab color space.
The default vertical alignment value of table data (<td>) is incorrect.
Current: "vertical-align: top;"
Expected: "vertical-align: middle;"
Workaround: Explicitly set the "vertical-align: middle;" of <td> elements.
Invalid content after updating empty password-protected archive.
Workaround: Instead of creating an empty archive, add a dummy file to it that can be removed later.
