This fully works as "expected", however it seems strange when there is no selected vertex in the non-active object. In 2.7x if you join two monkeys, select a vertex in one of them and try to use this operator in the other it will select the lonely newly selected vertex. If you split both monkeys and do this in 2.8 while multi-editing them you won't get nothing when trying to ctrl+RMB any vertex in the monkey object that has nothing selected yet. I propose to have this addressed in an upcoming patch where we always select a vertex if no vertex was previously selected.
