tabview tabviewstyle sidebaradaptable in macos 15.1. beta 5 is non responsive

Whan using a tabview set with a tabviewstyle of sidebaradaptable on macOS 15.1 beta 5 the tabs are non responsive and is basically broken.

Example code... If you click around on these tabs you will see it is not responsive. When you add a lot more tabs from a for loop for example you really get poor performance. But this is not the case with earlier beta releases.

TabView {

                Tab("One", systemImage: "1.circle.fill") {

                    Text("Test One")

                }

                Tab("Two", systemImage: "2.circle.fill") {

                    Text("Test Two")

                }

                Tab("Three", systemImage: "3.circle.fill") {

                    Text("Test Three")

                }

            }

            .tabViewStyle(.sidebarAdaptable)

I had the same experience. Only on macOS, sidebar not mouse responsive, a little bit with keyboard arrows. On iOS, TabView behaves as expected

Xcode 16.1 beta 2 MacOS Version 15.1 beta (24B5055e)

I am testing with Xcode 16.1 beta 1. Side note on Xcode 16.1 beta 2 charts fail with a build error. I think this issue is mac 15.1 beta 5 (24B5055e) only.

this issue remains in macOS 15.1 beta 6 24B5070a

Some more information here. This persists with the latest 15.1 beta 7 (24B5077a), however if you click to the far right of the tab, it works fine. It seems to only be if you click on the tab button where text is.

This still persists with macOS 15.1 release candidate 1 (24B82)

Apple replied to my feedback ticket on this issue saying they think it's fixed in macOS 15.2 Beta 2. I currently don't have the 15.2 beta installed on a Mac to confirm. Does anyone have the beta installed to see if this issue is fixed?
