Description
I have read and understood the contribution guidelines.
When a pdf file is generated via the html method in certain setups (with nested html elements and background-color styling specified), some part of text is not visible. You can still select the text in the pdf file, however it seems that the text has the same color as its background which makes it impossible to see.
Since this is a bit difficult to reproduce, here is a jsfiddle example that generates a file and has the described issue:

This might be related to an issue with html2canvas as I observed such results when directly using html2canvas. This is the reported issue in html2canvas:
