Bug in Building a Role Playing Game - Step 51

Hi,
i think i got a little bug, that probably shouldn’t pop up, while trying to completing Step 51 in the Building a Role Playing Game challenge.
I’m using “Opera One(Version: 106.0.4998.66)” as my browser and get a bug in the preview window, when I declare the variable wrong,

If I set the new variable that should be

const locations = [];

instead as

var location = [];

or

const location = [];

the preview window of the role playing game changes and displays instead the freecodecamp code window again. Additionally the “Check your Code” button doesn’t work.
I know that my mistake is the missing “s” at the end of the variable name, but this “bug” should probably not happen?

Is that an unknown bug I should report on github?

check the spelling of your variable

if the check your code button isn’t working, that means there’s an error with your javascript code, usually a syntax error such as semicolon or something

I know that my mistake is the missing “s” at the end of the variable name and i know how to fix it, but i was just wondering if this “bug” should be possible in the code editor.

There is an open discussion about it on github
