Fail to reder pdf because of recursive rendering image resource in html content

Hi Dan,

Something I encountered lately when playing around with openhtmltopdf lib. I don't know if this a known (if so sorry for this duplicate ticket) or even an issue. Following scenario example: I am rendering HTML content to a PDF file. In the HTML content there is an image tag, with com.openhtmltopdf.load -> com.openhtmltopdf.match -> com.openhtmltopdf.load -> com.openhtmltopdf.match ...

This is happening because the scenario looks like it tries to load image/pdf into image/pdf recursively.

The question is, should openhtmltopdf detects this recursive call and catch with an exception or is this something the service application needs to handle?
