- A page action or timer whose edits are refused shows nothing it did:
view changes go in only after apply_script_outcome accepts them.
- js_advance runs at most its 6,000-run cap; the last call only moves
the clock (Session::run_timers_at_most).
- Field callbacks see the document's layers (getOCGs), also after a
batch rebuilds the runner.
- The viewer's hit test uses what scripts show (shown_by_scripts): a
frame they showed takes presses, one they hid doesn't.
- Print previews draw without the live annotation and appearance
overrides.
- An appearance override naming no form (a cleared icon) draws nothing
instead of the button's own face (hayro patch 105).
- Page actions and timers wait while a dialog or prompt is open.
- A timer editing the focused field refreshes its untouched draft.
