[Bug] 关于鼠须管在tauri调试中不能输入中文、也无法切换中西的问题

[f91kdash]

tauri（mac系用的是WKWebview）调试中input框输入不了中文，但编译后的app能正常输入。
mac自带输入法没有这个问题。

鼠须管版本是1.0.2，没有任何改动

可否给个复现方法，谢谢。

做了多种尝试，xcode中无论是objc还是swift还是swiftui中使用webview都没有出现input框中无法输入中文的问题。但只要是rust，无论是用tauri还是通过objc crate创建的webview窗口就都会出现无法输入中文的问题，也不管是debug还是release。
编译出来的程序直接运行能正常输入。

可否给个可以无脑跟的步骤? 我甚至不知道从哪下手复现。你可以假设我已经安装了 Rust 工具链，但是具体要加什么 dependencies ，代码又是什么？

随便做了个演示。
先在终端安装上cargo-bundle: cargo install cargo-bundle
然后下面是代码:

Cargo.toml

[dependencies]
objc = "=0.2.7"

[package.metadata.bundle]

identifier = "com.a.demo"
icon = ["icon/icon.png"]
version = "1.0.0"
short_description = "An example application."

随便load一个页面，本地也行，http也行，只要有input框就能复现。
cargo run和build，都会出现无法输入中文的情况，但运行cargo bundle打包出来的app直接运行就能正常输入。无论debug还是release都一样。
我还测试了直接在终端运行safari，没有能复现，说明不是由终端启动应用导致。
系统14.6.1，鼠须管1.0.2
注：bundle的时候随便往项目下icon文件夹塞个icon.png就行。
