<details> Section Is Not Collapsible

[teschste-reyrey]

Is your feature request related to a problem? Please describe.
I need to be able to display collapsible examples using the "details" tag but it is not working in v1.16.263, I am assuming it is not implemented.

Describe the solution you'd like
Add support for collapsible "details" sections.

Describe alternatives you've considered
The only other option is having extended text with some type of delineation, which looks bad.

Additional context
One of the details sections I am tryin to implement (the attached image shows how it is actually displaying):

Display a tooltip anywhere across a single ListViewItem

Include the following code in the ListView's MouseMove event (replace the ToolTip1 parameter with the actual ToolTip control being used).

This code assumes the tooltip text is stored in the ListViewItem.Tag property.

Static previousPoint As New Point(-1, -1)

ListViewShowToolTip(sender, MousePosition, ToolTip1, previousPoint)

The calling form should also include a MouseLeave event on the ListView that includes the following code to ensure
the ToolTip is cleared right away if the mouse moves off of the ListView item (replace the ToolTip1 parameter with
the actual ToolTip control being used):

ToolTip1.Hide(sender)

(blank line)
