Paste doesn't always work as expected in broadcasted panes

The pane broadcast functionality that's currently in preview does not describe nor allow to configure how paste functionality works.
Currently, if you paste into a broadcast group of panes using right-click, it only pastes in the pane that the mouse is hovering over.
On the other hand, if you paste using Ctrl-v, it inconsistently pastes into _some_ of the broadcast group panes - but usually not all.

It would be nice if there was a configuration option that specified how to handle paste with a broadcast group.
And, the Ctrl-v paste should be consistent and either configurable or follow the same behavior as right-click.
