The requirement is only removing browserName from focusEditor calls.

Please keep the other functions as is.

Thanks for addressing the feedback. We're close.

browserName is now an unused variable here: https://github.com/freeCodeCamp/freeCodeCamp/pull/55246/files#diff-7bcc7e0b7d5a4a4c73ec6a263b7e3b3a0edc66c798bea820051c2c689ec806c2R26. And it should be removed.
