If I recall, the results tab is just a WebBrowser from the System.Windows.Forms namespace, which is just IE. However, there's now WebView2, which is a browser that's chromium based: https://docs.microsoft.com/en-us/microsoft-edge/webview2/ . I have installed the Canary build of edge and would love to try out LINQPad with that as the results window instead of the IE-based version.
