Lite: SnoozeBalloon dismiss/snooze buttons do nothing — popup persists indefinitely

[erikdarlingdata]

Problem

In Lite, clicking Dismiss, Snooze 15m, Snooze 1h, or Snooze 4h on an alert toast (SnoozeBalloon) appears to do nothing — the popup stays on screen. Users report having to click Dismiss dozens of times for a single alert.

Root cause

SnoozeBalloon.CloseBalloon() was raising Hardcodet's TaskbarIcon.BalloonClosingEvent and assuming the library would tear the popup down in response. It does not.

In Hardcodet.NotifyIcon.Wpf 2.0.1, BalloonClosingEvent is a notification the library emits when it closes a popup (from TaskbarIcon.CloseBalloon(), which is called internally on ShowCustomBalloon replacement and on timeout). There is no class handler that converts a balloon-initiated raise of that event back into a CloseBalloon() call.

// from Hardcodet TaskbarIcon.CloseBalloon():
RoutedEventArgs eventArgs = RaiseBalloonClosingEvent(element, this);
if (!eventArgs.Handled)
{
    popup.IsOpen = false;          // <-- only happens when LIBRARY closes
    RaiseBalloonClosedEvent(...);
    ...
}

So:

• Library-initiated close (timeout or replacement-on-new-show) → popup closes ✓
• User-initiated close (dismiss/snooze button) → routed event bubbles into the void, popup persists ✗

_closed = true in SnoozeBalloon silenced subsequent click handlers, so the popup couldn't even be re-dismissed — it just sat there until the next refresh tick replaced it with a fresh alert.

Fix

SnoozeBalloon now receives an Action closePopup callback at construction. SystemTrayService.ShowSnoozableNotification supplies () => _trayIcon.CloseBalloon(). The dismiss/snooze handlers invoke it directly instead of raising the routed event.

How it was diagnosed

Added per-instance lifecycle logging (SHOW/LOADED/USER_DISMISS/RAISE_CLOSE/CLOSING_EVT/CLOSED_EVT/UNLOADED) and reproduced via HammerDB load. Log showed CLOSING_EVT #2 firing on each dismiss click but never CLOSED_EVT #2 and never UNLOADED #2, confirming the library wasn't closing the popup.
