In addition to screen resolution and scaling, the text size setting under Accessibility also affects the zoom level of WebView2 content. Currently, Tauri only supports the former; please add support for the latter as well.

let text_scale_factor_value = text_scale_factor_key
.get_value("TextScaleFactor")
.unwrap_or(100u32);
