It looks like this actually happens when any attribute in an element using spreads (or prop in a component using spreads) has two or more dependencies. It's an order of operations thing. In the code for this REPL example, we're generating changed.visible || changed.value && { value: ctx.visible ? ctx.value : '****' } when we ought to be generating (changed.visible || changed.value) && { value: ctx.visible ? ctx.value : '****' }. We need to make sure we wrap the conditions here and here in parentheses as appropriate. PR coming in a bit.
