Description
Current Behavior
Markdown shortcuts automatically convert markdown-like input into formatted content (for example, bold, italic, and heading). However, shortcut transforms are not recorded as separate undo history entries. The transform is merged with the triggering text input, so undo also removes the user input instead of only reverting the transform.
