I'm currently working on a playwright test suite that requires a PAC Proxy server. While I can easily set the PAC proxy in Chrome using command line arguments and in Firefox using preference settings, I'm facing difficulty setting it on the WebKit browser used by Playwright. I found that WebKit has implemented PAC support for Webdriver ( https://bugs.webkit.org/show_bug.cgi?id=242792). I'm wondering if it's possible to expose these settings through a command line argument?
