Because the debit panel doesn't have focus when those refresh events fire.
refresh_handler is registered to the component manager
(gnucash/gnome-utils/gnc-component-manager.c) which runs all of the registered
event handlers when anything emits a qof_event or calls gnc_gui_refresh_all().
It's quite possible that some of those events have nothing at all of interest
to the reconcile window.
As long as the events aren't being put on the main loop then the emission
should be in the stack trace though it may be several frames down.

A g_closure is just a wee bundle containing the callback and parameters
registered to an event or a signal. Connecting to the signal or registering a
handler on an event adds the closure to a list and when the signal or event
fires it runs down the list calling g_closure_invoke() on each one. You
probably don't need to step into that. There should be a way to call the
'finish' command that runs the current stack frame to completion and stops at
the place it was called in the next one. Just do that until you get back into
GnuCash code unless you have a reason to thing that Glib or Gtk is doing
something wrong. That's unlikely in this case, it's more likely that either
deleting the split doesn't emit a QofEvent or something about the refresh
view's handler is filtering it out.
