macOS Sequoia 15.1.1 (24B91): Manifesting a thumbnail in purely black of Desktop 2 after adding it as opposed to Desktop 3, 4...

Curious of what kind of bugs Mac users concern in terms of Mac systems quality, I posted a bug as depicted below to which most of users probably pay no attention at all.

Yet it will smoothly manifest Desktop 2's thumbnail image as depicted below if you are observing the interface while adding another desktop by a triple-finger sliding again.

A funny bug, isn't it?
