### Expected behavior

`+eval/repl` & `+eval/send-region-to-repl` to work

### Current behavior

`+eval/repl` only works the first time. Subsequent usage of that command & `+eval/send-region-to-repl` will just print that code to the current buffer:

After trying the above command for interacting with buffer, `+eval/region-or-buffer` also stop working.

### Steps to reproduce

1. Open any racket file
2. Run `+eval/buffer-or-region`, observe that this work
3. Run `+eval/repl`
4. Run `+eval/send-region-to-repl`, observe weird behaviour where everything get copied & pasted to the current buffer
5. Run `+eval/buffer-or-region`, this now no longer work. Oddly enough, it will now either copy & paste the first line of the buffer, or ask for a branch to get some commit?
