The limit was never raised. The OpenGL fixed function pipleline only
supports a maximum of 8 light sources, this has been true for the last
20 years.

That's a bug, there's a jira entry for it somewhere.

This isn't a fare comparison. Kirsten's viewer has deferred rendering
enabled by default, which lets it render an effectively infinite
number of light sources. The official viewer still uses the fixed
function lights since the deferred rendering code isn't quite
production ready.

If you test again with them both using either deferred or fixed
function lighting they will behave the same.
