=== test-11180-g-teardown-mouse-decoy start ===
01 --- APPLY ENTRY to fO (park focus in secondary window W2) ---
02 --- now CLICK fT - the SECOND field - in the default window ---
03 frmT   ENTRY  <== target FRAME ENTRY (not expected on FWD: same frame)
04 fDecoy ENTRY  <== fallback NOT silent (contradicts jdb evidence)
05 frmO   LEAVE  (begin - delete secondary WINDOW W2, NO APPLY)
06 frmO   LEAVE  (end - no APPLY performed)
07 fDecoy LEAVE  <== fallback landed here, click drove a real change
08 fT     ENTRY  <== clicked target ENTRY (dropped by the parent probe)
09 --- F5: settled FOCUS is now: FILL-IN/fT
