[Bug] Duplicated tab/backspace/arrow keys in code editor

This is an error report.

Error details

Whenever I try to tab, it inserts 8 spaces instead of 4. When I try to backspace, it deletes two characters instead of one. When I navigate with the arrow keys, it moves two positions instead of one. However, typing alphanumeric characters works fine. This also does not occur in my local editor (e.g. VS Code), or in the text box that I'm currently typing in to fill in the error details.

I've tried refreshing the page, but it does not fix it. This is the first time I've seen this issue, and I've been using TheConstruct courses for a couple of weeks.

It works fine in Chrome, so may be a Firefox specific issue.

I suppose it’s even specific to your Firefox installation, because it’s not happening here. :thinking:
