Short description of error

Since the drop-down menu for How to sync Playback got moved
into the Playback drop-down menu, its ability to be keyed got broken.

2.80 and onwards opens these keyed properties correctly
(from 2.97b and earlier), but does not allow any control over the
keyframe(s) from the context menu or keyboard shortcuts.

Exact steps for others to reproduce the error from scratch

  • Open a broken version
  • In the timeline editor --> Playback drop-down menu
  • Over the How to sync Playback try inserting a keyframe (right-clicking or pressing I)

I can confirm, in blender 2.79 it used to work:

Apparently properties inside popovers can't be animated.

Yeah, there's a couple more irregularities, in the playback popover: Mute Audio & Audio Scrubbing.
Context menu keying options are available (in 2.8x & 2.7x), but do not work in 2.8x or 2.7x.

Keying this property via Python (bpy.context.scene.keyframe_insert('sync_mode')) works fine, so it seems to be a UI issue. ui_context_button_active(…) returns NULL when called from this stack:

ui_context_button_active(ARegion * ar, _Bool (*)(uiBut *) but_check_cb) (…blender/source/blender/editors/interface/interface_handlers.c:8201)
ui_context_rna_button_active(const bContext * C) (…blender/source/blender/editors/interface/interface_handlers.c:8214)
UI_context_active_but_prop_get(const bContext * C, struct PointerRNA * r_ptr, struct PropertyRNA ** r_prop, int * r_index) (…blender/source/blender/editors/interface/interface_handlers.c:8243)
insert_key_button_exec(bContext * C, wmOperator * op) (…blender/source/blender/editors/animation/keyframing.c:2367)
wm_operator_invoke(bContext * C, wmOperatorType * ot, wmEvent * event, PointerRNA * properties, ReportList * reports, const _Bool poll_only, _Bool use_last_properties) (…blender/source/blender/windowmanager/intern/wm_event_system.c:1453)
wm_operator_call_internal(bContext * C, wmOperatorType * ot, PointerRNA * properties, ReportList * reports, const short context, const _Bool poll_only, wmEvent * event) (…blender/source/blender/windowmanager/intern/wm_event_system.c:1688)

wm_handler_ui_call(bContext * C, wmEventHandler_UI * handler, const wmEvent * event, int always_pass) (…blender/source/blender/windowmanager/intern/wm_event_system.c:624)
wm_handlers_do_intern(bContext * C, wmEvent * event, ListBase * handlers) (…blender/source/blender/windowmanager/intern/wm_event_system.c:2756)

wm_event_do_handlers(bContext * C) (…blender/source/blender/windowmanager/intern/wm_event_system.c:3387)
WM_main(bContext * C) (…blender/source/blender/windowmanager/intern/wm.c:417)
main(int argc, const char ** argv) (…blender/source/creator/creator.c:518)

As a result, the insert_key_button_exec function doesn't know which property is supposed to be keyed, and it cancels the operator.

As this seems to be a UI issue, I'll leave the decision whether this is a bug or a known issue to the UI module team.

@William Reynish (billreynish) @Julian Eisel (Severin) can you shed some light on this?

I'm quite sure this is the same issue as T71472. Will merge the report, we can reopen if my guess turns out to be wrong.
