When exporting a page containing a Viewport redirect macro (from Scroll Viewport), the export will fail and produce an error zip. This behaviour has been introduced in v3.9.5.
Steps to reproduce:
Create Page A in a space with Scroll Viewport active
Add the Viewport redirect macro to Page A and define a URL
Save and export the page
Expected result: The page exports successfully
Actual result: The export fails and produces the following stacktrace
Wrap the Viewport Redirect macro in a Scroll Ignore macro
