I have encountered a strange behaviour with NodeViews.
I have a case where in addition to the basic prosemirror schema, I have a
section node, which can have any number of blocks as content (e.g. paragraphs).
section node I want to take control and use a NodeView to render it.
Now, let’s say I wrap a paragraph in a section block and then hit undo.
Even though the
section node no longer exists in the state, the nodeview itself appears to be in the dom.
I’ve created an example here to demonstrate: https://codesandbox.io/s/modest-meninsky-rgxbq?file=/src/App.js
- Focus on “Hello” and then click on the “Wrap in section” button
- Undo (using shortcut e.g. cmd + z)
(Please make sure you refresh the page if you want to repeat the experiment)
I would expect the paragraph to be rendered as whatever the paragraph schema defined (i.e. a
p tag) but instead it’s rendered inside a
pre, which is what is used by the
Is this the expected behaviour? Shouldn’t the
section NodeView be destroyed and then replaced by a paragraph nodeview?
