Steps to reproduce the problem:
1. Make multiple bookmarklets.
2. Put them in a folder.
3. The bookmarklets open an about:blank tab for each of them, along with any other normal bookmarks acting as normal.

What is the expected behavior?
The bookmarklets would either all run at once async, or at least in some order due with javascript's single threading.

What went wrong?
They're treated as normal bookmarks, and open in a new tab as normal bookmarks would.

Did this work before? N/A
