No guarantee that it’ll actually work when it does pop up, but I noticed that if I used kill 1 in the shell before or after clicking the stop button, it does at least bring up the output window for me everytime.
First run on a fresh repl it brings up the output, if I then close the output every run after that it doesn’t pop back up, I can manually re-open it though. But I tried opening it by just clicking run 6 times without it working. (this might be expected behavior though?)
If I enter kill 1 while it’s still running or after it has already been stopped, the output will consistently appear either immediately or on the next run.
