[BUG] Markdown Symbols Remove Existing Block

[mdsaban]

Has this bug been raised before?

• [X] I have checked "open" AND "closed" issues and this is not a duplicate

Description

When using markdown symbols (e.g., #, - ) to convert an existing text block into a heading or bullet list, the entire text block gets removed, leaving a blank block with the new markdown format. The existing text block should be retained and converted to the specified markdown symbol format (e.g., heading or bullet list) without losing content.

Steps to Reproduce:

• Create a new text block with any content.

@Darginec05, are you aware of this? If it hasn't been addressed yet, I'd be glad to investigate further.

@mdsaban I remember this issue, but I didnt have time to check this. So, I'll be happy if you will investigate.

I think the problem can be found in packages/core/editor/src/extensions/shortcuts.ts
