I took my dent along to Luxen's VaultRaid last sunday,, and was destroyed in fairly short order. However, I did manage to take Honey111 with me with my hull explosion. This was recorded in my pvp report, as well as my PK counter, but not by the Enduring Title.

Intentional or not?

Thanks for the report. That was not intentional. We'll add new kills made this way to the Enduring Title history.
