Error not showing in web app

[dipamsen]

Description

With CeTZ, using the cli the following code gives an error:

#import "@preview/cetz:0.0.1"

#cetz.canvas({
  import cetz.draw: *

  set text(6em) // ERROR

  circle((0, 0), radius: 2, name: "c")
})

However the same does not give any error in the web app - it says "Your document contains no errors", but editing the app does not update the output. (See reproduction URL) Also on refreshing the page, the output doesn't show up, but no errors are logged.

Here's another such example I found:

MWE:

#import "@preview/cetz:0.0.1"

#cetz.canvas(length: 3em, {
  import cetz.draw: *

  circle((0, 0), radius: 1)
  content((), [Hello])
})

This example errors in the CLI (https://github.com/johannes-wolf/typst-canvas/issues/99) but just hangs in the webapp, not updating the output, with no error.

Same with tablex

#import "@preview/tablex:0.0.4": tablex

#tablex(
  map-cols: (i,cells) => none,
  [Hello world]
)

leads to

error: panicked with: "Tablex error: 'map-cols' returned something that isn't an array."

     │ ╰─────────^

but the web app claims that "Your document contains no errors.", while also not outputing anything.

Is this for any panic() in a package?
