A question I had commented on vanished; no history

Recently there was a question concerning the conversion of formulas from LATEX and their formatting. At least @mikekaganski and myself had commented on that question, and there also was an answer (no longer sure by whom) pointing to a related extension.

As the question was somehow interesting to me, and since I was concerned about harmonizing formats in different situations (dates and date-time values in textfields and the like e.g.) I considered the question in a specific way, wrote some user code for the task, and wanted to get back to the mentioned thread to decide if I should post there.

I cannot find it again despite the fact that I know relevant keywords. There is also no mention of it either in my ‘Activity’ history nor in that of Mike.

What’s the reason?

There is a technical problem with history/notifications here on the site … it’s really inconvenient with that.

Yes, notifications have become totally unreliable.
