document that changing additional_browser_args require changing data_directory if multiple webviews will be opened

[Elendiar]

Describe the bug

Applying additional_browser_args, empty or not to any window builder during app_setup.

[2024-09-26][06:10:44][tauri_runtime_wry][ERROR] failed to create webview: WebView2 error: 
WindowsError(Error { code: HRESULT(0x8007139F), message: "The group or resource is not in the correct state to perform the requested operation." })

I create few windows during app setup, main, popover etc, and notice bugged behaviour when additional_browser_args applied to any on them.
For example, if use additional_browser_args("--enable-features=msWebView2EnableDraggableRegions --disable-features=ElasticOverscroll"), or .additional_browser_args("") to main window builder - i get HRESULT(0x8007139F) on any webview create from javascript frontend (ts/react).
But other windows, created from rust frontend works.
If i apply additional_browser_args to my secondary, popover window, webviews creates from js successfully, but interaction with popover webview, created from rust backend causes panic.

Applying additional_browser_args for both, main and popover window cause only failed to create webview: WebView2 error fro js, without panic.

i get HRESULT(0x8007139F) on any webview create from javascript frontend (ts/react).
But other windows, created from rust frontend works.

That part doesn't make sense to me tbh. It's not documented properly but every different additional_browser_args config also need a different data_directory config (so as long as the browser args are the same, they can share a directory). If you don't do this you get the "not in the correct state" error.

I mean that from frontend webview created without any arguments, there is no such property new WebviewWindow(label, {...}, but if any window with additional_browser_args builded in rust, i get this error.

That is, in order for this error not to occur, you must also specify data_directory when specifying additional_browser_args in rust builder?

Yes
