winform: ToolTip.AutoPopDelay max value mismatch with actual behavior

[LeafShi1]

Describe the issue or suggestion

The official documentation states that "the maximum delay for popups is 5000 milliseconds." This does not match actual behavior.

Current Behavior:

• On Windows 11, when ToolTip.AutoPopDelay is set to its default value of 5000 milliseconds, the tooltip remains visible indefinitely (infinite tooltip).
  This is due to WCAG 2.2 accessibility compliance requirements, as keyboard-accessible tooltips must be persistent and dismissible by default. Users can dismiss the tooltip by pressing the Escape key.

• When ToolTip.AutoPopDelay is set to a non-default value, the tooltip remains visible for the set duration.

This issue appears to have been fixed in PR #11863, which was merged on September 29, 2025.

The documentation for ToolTip.AutoPopDelay now includes platform-specific behavior notes:

• On Windows 10, the maximum time you can delay a popup is 5000 milliseconds. Values greater than 5000 ms are
  clamped to 5000 ms.
• On Windows 11, the default value causes tooltips to remain visible indefinitely. When set to a custom value,
  there's no 5000 ms limit, and the tooltip displays for the specified duration.

This should resolve the confusion about the behavior. Can this issue be closed?
