[BUG] RadioButtonGroup orientation doesn't have expected effect

[sdc50]

versions:

python: 3.9.5
jupyterlab: 3.0.16
bokeh: 2.3.2

When setting the RadioButtonGroup orientation attribute to 'vertical' I would expect the buttons to be stacked on top of each other vertically (something like rotating the horizontal version 90 degrees):

(but with the text oriented horizontally)

However, it seems that they are just stretched in the vertical direction:

I'm can't see how this would be useful, so I'm assuming this is a bug. It would be great if orientation='vertical' would stack the buttons on top of each other vertically.

I think either (or both!) of these options would be suitable for an orientation='vertical' configuration.

Orientation is not implemented on button groups at all, it's just bad design decisions that lead to it inheriting orientation property from Widget model. Though it shouldn't be too hard to make it work.

inheriting orientation property from Widget model

When did orientation get added to Widget ??

Awhile back. It's a side effect of JS/TS not having decent support for mixing code in.
