fix(dialog): prevent unintended dialog closure on releasing pressing

[songkeys]

Problem

When users try to select text within a dialog, if they start the selection inside the dialog but move their cursor outside and release pressing, it would unexpectedly trigger the dialog to close. This creates a poor user experience, especially when users are trying to interact with text content (e.g. move to select something).

Solution

Implemented press state tracking to ensure the dialog only closes when both the press start AND end events occur inside the background area.
