If you check out the original header, there's not much i can actually expose:

positron/src/wv/webview.h

Lines 37 to 108 in e8954db

 // Creates a new webview instance. If debug is non-zero - developer tools will 

 // be enabled (if the platform supports them). Window parameter can be a 

 // pointer to the native window handle. If it's non-null - then child WebView 

 // is embedded into the given parent window. Otherwise a new window is created. 

 // Depending on the platform, a GtkWindow, NSWindow or HWND pointer can be 

 // passed here. 

 WEBVIEW_API webview_t webview_create(int debug, void *window); 

 // Destroys a webview and closes the native window. 

 WEBVIEW_API void webview_destroy(webview_t w); 

 // Runs the main loop until it's terminated. After this function exits - you 

 // must destroy the webview. 

 WEBVIEW_API void webview_run(webview_t w); 

 // Stops the main loop. It is safe to call this function from another other 

 // background thread. 

 WEBVIEW_API void webview_terminate(webview_t w); 

 // Posts a function to be executed on the main thread. You normally do not need 

 // to call this function, unless you want to tweak the native window. 

 WEBVIEW_API void 

 webview_dispatch(webview_t w, void (*fn)(webview_t w, void *arg), void *arg); 

 // Returns a native window handle pointer. When using GTK backend the pointer 

 // is GtkWindow pointer, when using Cocoa backend the pointer is NSWindow 

 // pointer, when using Win32 backend the pointer is HWND pointer. 

 WEBVIEW_API void *webview_get_window(webview_t w); 

 // Updates the title of the native window. Must be called from the UI thread. 

 WEBVIEW_API void webview_set_title(webview_t w, const char *title); 

 // Window size hints 

 #define WEBVIEW_HINT_NONE 0 // Width and height are default size 

 #define WEBVIEW_HINT_MIN 1 // Width and height are minimum bounds 

 #define WEBVIEW_HINT_MAX 2 // Width and height are maximum bounds 

 #define WEBVIEW_HINT_FIXED 3 // Window size can not be changed by a user 

 // Updates native window size. See WEBVIEW_HINT constants. 

 WEBVIEW_API void webview_set_size(webview_t w, int width, int height, 

 int hints); 

 // Navigates webview to the given URL. URL may be a data URI, i.e. 

 // "data:text/text,<html>...</html>". It is often ok not to url-encode it 

 // properly, webview will re-encode it for you. 

 WEBVIEW_API void webview_navigate(webview_t w, const char *url); 

 // Injects JavaScript code at the initialization of the new page. Every time 

 // the webview will open a the new page - this initialization code will be 

 // executed. It is guaranteed that code is executed before window.onload. 

 WEBVIEW_API void webview_init(webview_t w, const char *js); 

 // Evaluates arbitrary JavaScript code. Evaluation happens asynchronously, also 

 // the result of the expression is ignored. Use RPC bindings if you want to 

 // receive notifications about the results of the evaluation. 

 WEBVIEW_API void webview_eval(webview_t w, const char *js); 

 // Binds a native C callback so that it will appear under the given name as a 

 // global JavaScript function. Internally it uses webview_init(). Callback 

 // receives a request string and a user-provided argument pointer. Request 

 // string is a JSON array of all the arguments passed to the JavaScript 

 // function. 

 WEBVIEW_API void webview_bind(webview_t w, const char *name, 

 void (*fn)(const char *seq, const char *req, 

 void *arg), 

 void *arg); 

 // Allows to return a value from the native binding. Original request pointer 

 // must be provided to help internal RPC engine match requests with responses. 

 // If status is zero - result is expected to be a valid JSON result value. 

 // If status is not zero - result is an error JSON object. 

 WEBVIEW_API void webview_return(webview_t w, const char *seq, int status, 

 const char *result);

I guess for these features you have to either hack all three backends to support these features, but i'll keep positron a flat and simple wrapper around the webview library + an embedded web server for local loopback requests.

Ah, I guess it's better to open this feature request in the upstream webview library then👍
