Issue Summary

PDF export content is cropped when left/right margin is >= 2cm. Also, the A4 Size: 210mm x 297mm is not working 
Note: @page will fallback to V1 export experience so it doesn't matter if pdf export v2 is enabled or not.

Steps to Reproduce

1. Create a page with some content 
2. Add pdf export stlesheet with A4 page size and Page margin 2 cm 
   Eg. 

   @page {   size: 210mm 297mm; /* A4 */   margin-left: 2.0cm;      margin-right: 2.0cm;  

Expected Results

The exported page layout should be set as per the Margins defined in the PDF stylesheet.

Actual Results

After exporting this page, we found the content is cropped from the left/right side

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
