Mac Preview switches tabs several times

Why does Mac Preview switch tabs several times when I push Ctrl+Tab only once on macOS Big Sur?

I have two windows of Mac Preview open, of which one has two tabs. When I use the shortcut Ctrl+Tab in the app, it changes between the two tabs several times (about 6), with a delay of 3 seconds each. It only seems to happen when I move the mouse or use the zoom within a few seconds after switching tabs. Does anyone know to how to fix this bug?

Hmmm..
