Could you consider implementing UI for vertical writing?

Is your feature request related to a problem? Please describe.

When trying to implement a Japanese vertical writing editor, the style gets disrupted.

Describe the solution you'd like

I would like it to take a direction prop, and if it's 'vertical', have it work in vertical writing as well.

Describe alternatives you've considered

Evaluate with a prop like vertical: boolean Configuring the CSS myself (when it becomes vertical writing, a significant amount of rewriting becomes necessary, making it hard to accommodate future updates).

Additional context After i added some style

body {
  text-orientation: upright;
  -ms-writing-mode: tb-rl;
  writing-mode: vertical-rl;
}

The screen looks like the attached image and is out of style.

• placeholder
• slash menu
• format menu

Should I customize CSS on my own? Or could you consider implementing UI for vertical writing?
