Quill: Adding allowedChildren to blockquote setting throws an error

[icewind7030]

I want to prevent some blots such as image from being wrapped in block such as blockquote.
I could use

Blockquote.allowedChildren = [Inline, Text];

to customize the quill source code, and It work.
The problem is: although prevents image from being wrapped by blockquote, it also throws an error

Uncaught Error: [Parchment] Cannot insert image into blockquote

That is not what I want, what should I do to prevent image from being wrapped in other blocks?

I'm also having a similar problem. Wanted to tweak out Header format to 'clean' up formats by doing:

var Header = Quill.import('formats/header');
var TextBlot = Quill.import('blots/text');
Header.allowedChildren = [TextBlot];

But I'm also having the error:

[Parchment] Cannot insert bold into header

And then it applies a delete op of the blots/contents up until the bold blot.

It just seems to be reaching this point, coming from moveChildren and throws the error...

I always thought that adding to allowed children would clean up non allowed formatting/blots inside a container/block. 😕 Bummer.

allowedChildren is not meant to correct invalid input. To do what it sounds like you guys want you would extend Header/Blockquote and modify insertAt to not do anything if given an image.

var BaseHeader = Quill.import('formats/header');
class Header extends BaseHeader {
  insertAt(index, value, embedValue) {
    if (value === 'image' && embedValue) return;
    super.insertAt(index, value);
  }
}

Quill.register(Header, true);
