 More than once, I lost comments to track. My current hypothesis is that I
 accidentally clicked “Preview” instead of “Send changes” and closed the
 tab or browser afterwards, without noticing that I did not actually submit
 them.

 With the live preview, the Preview button is not as useful as it could be
 anyways.

 So maybe simply removing that button would do more good than harm.

 Erikd +1ed my request on IRC.
