Quarto render deletes PDF image assets

[sapphire008]

Bug description

Hi, I have an asset folder that stores svg and pdf version of the same image. My document references the svg version. When I run quarto render, the pdf version of the images are deleted. I have tested that if I convert the image to eps version or other image formats, these other variants do not get deleted by quarto render. I have tried with the --no-clean flag as well, but these images still got deleted. So my question is how can I keep the pdf version of my images around?

Here is a simple repository to illustrate the issue I am facing: https://github.com/sapphire008/quarto-pdf-deletion

Running quarto render deletes the file assets/sliding-moving-average.pdf.

Linking original question asked: #8297

Steps to reproduce

Checkout the repository https://github.com/sapphire008/quarto-pdf-deletion.git and run quarto render.

Expected behavior

I would expect the pdf files are being kept around.

Actual behavior

The pdf asset file is being deleted

Thank you! What's happening is exactly what I suspected: our pdf-images filter sees the document, sees an svg image, and wants to be helpful, so it converts the svg to pdf, but then deletes it because it thinks that this was an auto-generated file.

I think we need an option to disable this filter.
