11_RC6/i386 wsvt25 console issues

After updating an old i386 box from 10.1 -> 11_RC6 I noticed that
the lynx text browser displays some serious rendering issues in the
wscons screens (console + ttyE1-3) with TERM set to "wsvt25" or
"wsvt25m", particularly with colors enabled.  The only TERM value
that seems to work is "pcvt25-color".  I don't see this issue on
the amd64 port, just the i386 port.  Also, if I don't see the issue
if I run lynx under tmux with the standard "tmux" TERM value.

Not sure how I could generate useful debug data, perhaps someone
can suggest some approaches?
