Unfortunately, the bug is still present on the custom Popup Components. In this animation, you can see how the typical ComboBox Popups work correctly, but the custom Components are rendering incorrectly. Our preset menu isn’t showing up at all.
Was this behaviour present before the fix I posted above? I can’t reproduce it but it looks like you are trying to set the sizes of the
PopupMenu's custom components which is interfering with its own resizing - you should be using the preferred width/height options for custom components. In any case, it would be really helpful if you could send a minimal example that exhibits this behaviour so we’re seeing the same thing.
