I am working on a macOS app and I am programmatically adding NSToolbarItems following Apple's documentation - https://developer.apple.com/documentation/appkit/touch_bar/integrating_a_toolbar_and_touch_bar_into_your_app and I am adding the new NSTrackingSeparatorToolbarItem to support the new macOS 11 toolbar look and feel. The tracking separator seems to work fine as long as I don't resize the split view below a certain width, then the separator breaks out and just looks out of place. Is there a way to avoid this?? I don't want to hard code a minimum width, since the user might add items dynamically, and I just want to make sure that the split view does not force the tracking item to just pop out. I could not find any code examples showing the new macOS 11 toolbar functionality. On stack overflow I posted a question - https://stackoverflow.com/questions/64837040/how-to-avoid-nstrackingseparatortoolbaritem-from-overflowing-when-resizing-a-spl which shows 2 images with the described behavior. thanks in advance
