Fixes #31437

Possible cause

Ctrl+S is also registered as the StashMessage command in core/shortcuts.cpp, using Qt::ApplicationShortcut.

When the media viewer receives a QEvent::ShortcutOverride for Ctrl+S, the event filter returns true without explicitly accepting the event. This may allow the application-wide shortcut to take priority, preventing the media viewer from receiving the normal key press.

Fix

Call event->accept() when handling QKeySequence::Save or QKeySequence::SaveAs in OverlayWidget::filterApplicationEvent().

As described in the Qt documentation, a QEvent::ShortcutOverride must be explicitly accepted for the override to take effect.

Testing

Tested on Windows 11 with Qt 6:

• Ctrl+S opens the Save As dialog in the media viewer.
• Ctrl+Shift+S continues to work.
• Ctrl+S still performs the existing draft action in the chat editor.

The video below compares the original behavior with the fix:

• Left: Telegram Desktop 7.3.3 (dark theme, without the fix).
• Right: Locally built Telegram Desktop with the fix applied (light theme).
