NSButton 的 #selector(ViewController.backBtnClicked) 不适用于蒙特雷

所以我有一个 WKWebView &其顶部有一个 NSButton，其

backBtn = NSButton(image: NSImage(named: "NSLeftFacingTriangleTemplate")!, target: self, action: #selector(ViewController.backBtnClicked))

函数定义为

@objc func backBtnClicked(){}

This is for Swift MacOS app。

所有这一切都运行良好，直到蒙特利进行新升级。现在，WKWebView 在其中打开一个 PDF 以及其顶部的按钮。该按钮在加载 HTML 的其他视图中工作正常。它似乎不适用于 PDF 文件。

当您将鼠标悬停在 PDF 页面底部时，WKWebView 会出现此类选项，例如缩放或下载。 我的想法是，这些选项正在取代按钮点击，而蒙特利之前的情况并非如此。 所以我的问题是，

这是否是一个已知的错误，或者
是否有任何解决方法，或者
WKWebView 是否有任何设置选项，以便我可以在其中打开 PDF 文件时禁用这些选项

So I have a WKWebView & a NSButton on top of it with a

backBtn = NSButton(image: NSImage(named: "NSLeftFacingTriangleTemplate")!, target: self, action: #selector(ViewController.backBtnClicked))

with the function defined as

@objc func backBtnClicked(){}

This is for Swift MacOS app.

All of this was working fine until the new upgrade of Monterey. Now WKWebView opens a PDF in it and the button on top of it. The button works fine in other views that load HTML. It just does not seem to work with the PDF files.

WKWebView such options when you hover on the PDF towards bottom of page such as zoom or download. What I am thinking is that those options are overtaking the button click which was not the case before Monterey.
So my question is if

this is a known bug or
if there is any workaround or
if there is any setting option with WKWebView so that I can disable those option when a PDF file opens in it
