**Describe the bug** Given the following Markdown: ```  ``` The "Sample image" is the alt text and should be preserved as such. However the Block HTML for this looks like: ``` <img class="bn-visual-media" src="https://picsum.photos/200" alt="BlockNote image" contenteditable="false" draggable="false"> ``` **To Reproduce** This can be reproduced in the [BlockNote Playground](https://blocknote-main.vercel.app/interoperability/converting-blocks-from-md)
