Expected Behavior
Clicking a block in the workspace should cause it to run
Actual Behavior
If you have the sound or costume tab open and you add a new sprite, the blocks no longer run from the workspace, but they do in the flyout.
You can add a sprite either by random, uploading, or from the library, but not from painting a new one, to get this effect
Steps to Reproduce
Create a new project
Open the costumes tab for the cat
Add a surprise sprite
Drag a "go to random position" block to the workspace
Click the "go to random position" block
Note: nothing happens
