Column layout (e.g. `layout-ncol: 2`) not honoured in `panel: input`

Some Observable input elements do not follow the column layout inside panel: input blocks.

---
title: "input-col-test"
format: html
execute: 
  echo: false
---

# Heading

```{ojs}
//| panel: input
//| layout-ncol: 2
viewof is_a = Inputs.toggle({label: "A"})
viewof is_b = Inputs.toggle({label: "B"})
```

Wrapping it into :::{.panel-input} etc. does not help in this case.

I've observed this with toggles.

The alignment of the tickboxes against text vertically and spacing horizontally also seems odd - see below, although here the column layout is observed.

title: "input-col-test"
format: html
execute: 
  echo: false

# Heading

```{ojs}
//| panel: input
//| layout-ncol: 2
viewof is_b = Inputs.checkbox(["one", "two"], {label: "B"})
viewof is_a = Inputs.toggle({label: "A"})
```
