On MacOS when TabView is in sidebarAdaptable mode:
Clicking the Tab directly on the text of its label, or its systemImage, does not actually select the Tab.
The only way to select the Tab is to click whitespace around the text, for example to the right side of the text. iOS has behavior better – you can click the text or image to select the Tab.
This behavior is really bizarre and not user-friendly. I'm surprised it could even ship like this. Tabs are actually unusable in sidebarAdaptable because users should not have to be explained to that they need to click on whitespace.
Am I missing something? Seems almost too strange to be a bug.
