  -----------
  Eliminate needless focus reload

When deciding whether to rot the focus context, we no longer look
at what deltas were computed, but whether any deltas were really
executed (or failed to be executed).

This eliminates needless context rot, followed by context reload.
(That operation can be costly for large objects.)

Resolves MID-5830. Related to MID-7053 as well.
