> Namenode UI allows previewing both file's head and tail.
> However, it is malfunctioning if I preview another file after I close the
> previous modal.
> This bug is caused by duplicated events.
> Events are only added to "file-info-preview-head" and
> "file-info-preview-tail".
> Previous added events are not removed later.
