A terminal component blocks the execution of all subsequent viewers

[perellonieto]

If a code block includes the component terminal all the subsequent code blocks that have a viewer are not rendered (with quarto version 1.3.450).

The following is a code example that does not allow the 2 last code blocks to render.

```{shinylive-python}
#| components: [editor, terminal]

print('First code will prevent the rest of the code blocks from showing their rendered output')
```

```{shinylive-python}
#| standalone: true
#| components: [editor, viewer]
from shiny import App, ui

app_ui = ui.page_fluid("The text in the second code block is not shown.")

app = App(app_ui, None)
```

```{shinylive-python}
#| standalone: true
#| components: [editor, viewer]
from shiny import App, ui

app_ui = ui.page_fluid("The text in the third code block is not shown.")

app = App(app_ui, None)
```

Thanks for providing the very clear example. If there is a viewer block before the terminal, does it run?

I changed the title as I meant a terminal blocks the subsequent viewers.

If I only add a viewer to the previous code

```{shinylive-python}
#| components: [editor, viewer, terminal]

print('First code will prevent the rest of the code blocks from showing their rendered output')
```

it raises an error about the argument #| standalone: true being necessary.

If I add the #| standalone: true option

```{shinylive-python}
#| standalone: true
#| components: [editor, terminal]

print('First code will prevent the rest of the code blocks from showing their rendered output')
```

I raises the error '#| standalone: true' is not valid for editor-terminal and editor-cell code blocks. which may be related to this issue.

And if I add both the #| standalone: true option and the viewer

```{shinylive-python}
#| standalone: true
#| components: [editor, viewer, terminal]

print('First code will prevent the rest of the code blocks from showing their rendered output')
```

the page is rendered as expected. Then as indicated above the original problem is that the current implementation of the shinylive extension does not support a standalone terminal.

If this is correct, are there any plans to work on the standalone argument?
