Scissor state not saved with GL_ENABLE_BIT

Since NVIDIA driver versions 180.48 and 181.20 it seems the GL_SCISSOR_TEST is not saved by glPushAttrib(GL_ENABLE_BIT). It is necessary to include or use GL_SCISSOR_BIT to save the Scissor test state.

According to current documentation, page 285 of OpenGL 2.1 and page 362 of OpenGL 3.0, the scissor enable state should be saved by both scissor and enable groups.

Does anyone have any explanation or comment on this? It appears to be a driver bug…

Yeah, seems to be a driver bug, and still present in 182.06.
