[feat] Expose the ability to enable are_browser_extensions_enabled from CoreWebView2EnvironmentOptions

[SpikeHD]

Describe the problem

While I understand this would have to be Windows-only from the get-go (and a somewhat niche use-case), I'd like to not only load a custom extension (for use in overwriting request headers, something that can otherwise not be done in Tauri/Wry using external URLs), but also give my users the ability to load browser extensions as well.

To do so requires setting CoreWebView2EnvironmentOptions.set_are_browser_extensions_enabled(true) as well as calling AddBrowserExtension on the ICoreWebview2Profile7. While I can access the ICoreWebView2Profile7 and call that function (via WebviewWindow.with_webview and some casting), after some digging, I couldn't find a way to set this environment option to begin with.

Describe the solution you'd like

I haven't totally thought of the best way to go about this honestly, since it's as platform-specific as you can get, and I don't have a perfect understanding of the Wry & Tauri codebases.

I recently looked at this Wry PR (#1344) that implemented the ability to change the scrollbar style for Windows in Wry, but as far as I'm aware, this functionality isn't exposed in Tauri either, so I wouldn't know what the plan is/would be to do so (if there even is any). Assuming that does get exposed, the same methodology would probably apply to this as well.

Alternatives considered

Like most problems, I could probably solve it by just forking and maintaining a separate Wry and Tauri, but that sounds like a huge pain lol.

wry (#1344) needs a PR in tauri to be exposed and the author said they will open one.

We wouldn't want that, now would we? you could just open a PR 😉 (ofc if you want) and I will help land this in wry and tauri.

Hahaha fair enough, I will take a crack at the Wry portion sometime very soon!

[SpikeHD]

What would be the most sensible way to include platform specific options (like this or the scrollbar style thing) in Tauri? My heart tells me adding something like

let win = WebviewWindowBuilder::new(x, y, z)
  .windows_browser_extensions_enabled(true);

is kinda ugly but I can't really think of anything else off the top of my head

[amrbashir]

this is fine but I would just name it enable_browser_extensions and document that it only works on Windows atm

[SpikeHD]

Okay! The Wry PR is done (tauri-apps/wry#1356) so once that's in I'll get the Tauri PR going 💪

[SpikeHD]

Tauri PR opened! #11056

I tried to find this in the API of v2.0.6 but wasn't able to. Is it available yet?

[SpikeHD]

Yep, it's named browser_extensions_enabled on the WebviewWindowBuilder
