First Check

• I added a very descriptive title here.
• This is not a Q&A. I am sure something is wrong with NiceGUI or its documentation.
• I used the GitHub search to find a similar issue and came up empty.

Example Code

from nicegui import ui

ui.separator().props("vertical")

ui.run()

Description

Hi,

I noticed that my ui.separator.props("vertical") elements stretched to occupy all the horizontal space instead of just 1px after updating to NiceGUI 3.

It seems to stem from f571ff1#diff-5d9345fb48521f49b1b64d5d6e3cec49ab5a59b10621f21532e1d87613e3e69bR43

Can you advise on how to re-enable the "vertical" feature without having to add a style like ui.separator().props("vertical").style("width: 1px")?

Thanks!
Tim
