Hello
I have implemented an PopoverScrubber in the macOS Touch Bar
NSPopoverTouchBarItem contains an NSTouchBar which contains NSColorPickerTouchBarItem and an NSSliderTouchBarItem
The issue is that the NSColorPickerTouchBarItem appears for 1s then is dimissed... I don't understand why. I tried to file a bug report
but it was dismissed..
The console prints:
[Layout] Detected missing constraints for <NSFunctionRowColorPickerSlider: 0x100296b20>. It cannot be placed because there are not enough constraints to fully define the size and origin. Add the missing constraints, or set translatesAutoresizingMaskIntoConstraints=YES and constraints will be generated for you. If this view is laid out manually on macOS 10.12 and later, you may choose to not call [super layout] from your override. Set a breakpoint on DETECTED_MISSING_CONSTRAINTS to debug. This error will only be logged once.
