Is there any way to get the height of a panel programmatically?

[ZeroIntensity]

I need to get the height of a panel inside of a layout. I've looked through the documentation and wasn't able to find anything.
Panel.height exists, but that returns None if it wasn't set manually.

Here's an example of what I am trying to do:

from rich.layout import Layout
from rich.panel import Panel

layout = Layout()

layout.split_column(
    Panel("something"),
    Panel("another_thing")
)

something_height: int = layout["something"].height

The Panel.height is used to force the height in advance. It's not to report the height as it is rendered.

If you want to know the available height within a Panel you can define a console renderable with a __rich_console__ method. See the docs for how to define a console renderable. The options parameter will have a max_height attribute which is the number of lines available.
