Print PDF Tables as Line Items no longer working in 7.12 and 8.1

We use WYSIWYG fields in our Products.
If you have a table in that WYSIWYG field, it no longer prints columns correctly.
If your table is:
It will print the A and B on top of each other, and then next line/row has the C overwritten by the D.
It works correctly in 7.11, but 7.12 and 8.1 has this odd behavior.
A table directly inserted into the PDF template will print correctly, but if the table is in a Line Item, then it does not work.

I guess this was caused by the switch from mPDF to Tcpdf.
