Hello! To remove the commits that aren't yours, you can rebase your branch on top of the latest rc/v12.0.0 branch. This will remove any commits that were added to rc/v12.0.0 since you created your branch.

Here are the steps to do that:

1. Fetch the latest changes from rc/v12.0.0:

   git fetch upstream rc/v12.0.0

2. Checkout your branch:

   git checkout [your-branch-name]

3. Start an interactive rebase:

   git rebase -i upstream/rc/v12.0.0

4. In the editor that opens, identify the commits that aren't yours. These are likely the ones at the top of the list.

5. Change the word pick to drop for each commit you want to remove.

6. Save and close the editor.

7. Force push your changes to your branch: Note that force pushing is a dangerous operation because it overwrites commit history, so if you dropped the wrong commits you could lose work.

   git push -f origin [your-branch-name]

Once you've done this, the PR should only contain your commits.

Let me know if you have any questions or run into any issues!

Hiya @devesh-2002 Can you run npm run format in the root directory of blockly to fix the formatting failure?

Hiya @devesh-2002 Can you run npm run format in the root directory of blockly to fix the formatting failure?

Done. npm run format seems to have made changes in many other files, should I push those also? (I have pushed only 1 file right now, where I had made the changes)

Just pushing the changes to your files is perfect! Thank you for the fix this looks great =)
