Issue when trying to use the api example open_window() command.

[MostHated]

Hey there, I am having issues with the API examples (api.open_window() command). I came across a testing script in another thread and gave it a try to see if it was just me that was doing something wrong or not. I ran the script and ended up with the same issue as my original plugin: E5108: Error executing lua Value of type () couldn't be pushed on the stack: "non-float cannot have \'row\'".. When I ran the tests that were included in ths repo (using nightly nvim), all the window ones passed, which threw me off a bit.

Doing some searching on the issue, it seems like it may have something to do with setting row/column and then having to set the window relative setting again after that? Unfortunately, I don't know enough about the nvim backend yet to try and do much more diagnostic, myself, outside of doing something silly:

I didn't expect much from this, but figured it might be worth a shot, lol.

let config = WindowConfig::builder()
     .relative(WindowRelativeTo::Editor)
     .width(10)
     .row(3)
     .col(3)
     .relative(WindowRelativeTo::Editor)
     .build();

Upon running the script, it looks like there might be another issue with the mlua example that I had not noticed, but wanted to still report it.
