- Currently an unlimited amount of errors could be shown to the user, this can cause that if something goes wrong the user will be shown a big wall of errors, even when Forgejo in most cases can still be used. - Therefor limit to three errors being shown, as it's unlikely that three seperate javascript errors needs to be shown, they are likely to be related and the console still shows all of the errors.
