For the second program, it looks like a bad execution was cached. If you modify it slightly (e.g., add some trailing whitespace on one of the lines) and run it again, it works the same as the first program.

Do you remember when you created and ran that second playground program for the first time? There have been various improvements to the playground as part of #25224 recently, so this might be related to that.

When you slightly modify the program it works! I ran the second program the day before I posted this issue.
