Cannot run or submit a second time after closing popup window

[lourw]

To recreate:

1. Open a new question (27. Remove Element)
2. Submit your code (this opens the run/submit popup) using :Leet run or :Leet submit

3. Close the run/submit popup window with :q
4. Try to enter :Leet run or :Leet submit again.
5. You get this message:

You are not supposed to close this popup with :q as it needs to be persistent.

All of the popups inside leetcode.nvim have two shortcuts q and Esc for hiding them so the next time they get opened the previous state will stay.

Now, if you :q a popup, the state will still get erased. However, the next time you try to open it, it should mount again without any errors.
