New in-editor error popups can extend off-screen

Godot version

v4.0.alpha.custom_build [78e3e65]

System information

Windows 10

Issue description

The new error popups don't wrap text or otherwise handle longer text, so they can extend off-screen:

Since the errors are left-justified as a block, long errors can push shorter ones off-screen:

Popups don't seem to have been introduced in v4.0.alpha1.official [31a7ddb], so I haven't been able to reproduce the behaviour there.

**Edit: ** The bug also appears in alpha 1.

Steps to reproduce

Cause a sufficiently long error message to popup in the editor, e.g. with

@tool
extends Node

func _process(delta):
    var a
    a.loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong_function_name()

attached to a node in the scene tree.

Toasts were already implemented in 4.0alpha1, but did you make sure to enable them by clicking the bell icon?

Okay, confirmed that the toasts go off-screen in alpha 1 too.

enable them by clicking the bell icon

In alpha 1, this didn't enable them for me ( the same as #56550). It looks like the default behaviour for show_internal_errors_in_toast_notifications is Auto. In alpha 1, auto disabled them; in the custom build, it enabled them, I think due to them being official and development, respectively.

@groud can you implement some EDITOR_DEF for the label maximum width?

[akien-mga]

It probably doesn't need to be a setting, just a hardcoded percentage of the available window width.
