It seems that pronouns truncate one character too early.
For example, when setting the pronouns to "He/They/Fox" the resulting pronouns in the nameplate are "He/They/Fo..." -- Only the x is truncated, but the act of truncating them adds the "...", so surely there was space for the x.
I'd expect the following behavior after fix:
"He/They/Fox" -> "He/They/Fox"
"He/They/Foxy" -> "He/They/Fo..."
