PDF preview is not a part of WebContent, rather a Safari plugin. It is outside of scope for Playwright testing.

I don't know what ENABLE_PDFJS is. But, GTK and WPE ports enable it.

There isn't much we can test / validate about the pdf viewer.

I think we'd much rather prefer that pdfs trigger downloads, like WK/FF are already doing as per #7822.

How can we add it in the config for enabling in webkit , like we have done for forefox above ?

There is no such config in Playwright.
