Expected Behavior

A "When I receive event" in a project should be able to receive broadcasts, given that the correct message name is used, from an imported sprite.

Sprite "Outfielder" is created in one project and exported as a sprite. It has a broadcast with the name "Backdrop 1". That sprite is imported into another project.

When clicked, it should broadcast that name and the "when I receive Backdrop 1 block" in the stage should start its script.

Actual Behavior

The "when I receive block" in the stage is not activated by a broadcast from an imported sprite. Both have the correct message name.

Steps to Reproduce

See the case study: https://scratch.mit.edu/projects/1168628637/

Steps:

1. Create a new project with the sprite "outfielder". Add a single script "when clicked" broadcast message "Backdrop 1".
2. Export the outfielder sprite.
3. Create a new project with banana sprite and add backdrops for "Bench with View", "Chalkboard", and "Canyon".
4. Add when I receive broadcasts for "Backdrop 1" and "Backdrop 2". "Backdrop 1" script switches to the Canyon backdrop and "Backdrop 2" switches to the
   Chalkboard backdrop.
5. Import the Outfielder sprite.
6. Click on the banana and see the Chalkboard backdrop.
7. Click on the outfielder and notice that nothing happens.
