Quarto VSC/positron extension keeps displaying "Rendering *file*.qmd" on errors

[JosephBARBIERDARNAL]

Bug description

When rendering a quarto document with the “Preview” button, if the document is interrupted (e.g. due to an error in the code), it will continue to display this:

Here, it's just an image, but the thing moves too.

Steps to reproduce

---
title: Title
---

```{r}
1 + "a" # this raises an error
```

Actual behavior

No response

Expected behavior

I wish it would stop appearing, because in most cases it's because there's something wrong with the code I've written, and I'll probably spend at least a few minutes before wanting to preview my document again. It's not the best to have this thing moving all the time, and having to close it manually (which works fine, by the way).

This really annoys me too! I would love for us to change the behavior around that notification so it resolves not only with a successful render but also if the rendering errors.

I'm able to reproduce in VSCode and Positron by clicking the preview button without having a preview pane open -- if the preview pane is open, the loader seems to go away upon the error appearing.

Fixed and merged! Will be fixed in the next Quarto extension release
