Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I quote code into the input box, type some text afterward, then paste another copied block of text into the box, undoing via keyboard shortcut deletes earlier text incorrectly. The pasted content cannot be undone properly, and the undo sequence is out of order. This issue occurs on the latest macOS system and the newest Cursor version, as well as Cursor’s latest Agents feature on Windows chat input boxes.

Steps to Reproduce

  1. In the input box, use Command+L to insert quoted code
  2. Type descriptive text after the code snippet
  3. Paste an additional copied block of code into the input field
  4. Press Command + Z to undo
    Result: The middle content gets removed first, newly added text undoes in the wrong chronological order

Does this stop you from using Cursor

Sometimes — I am still able to use Cursor most of the time

Indeed, that is something I experience myself too (the post was flagged because not in english, but it’s a real concern)
