Panel "Opaque" setting changed in Plasma 6?

As you can see in the screenshot above, in Plasma 6, the panel’s “opaque” setting seems to change from Plasma 5’s complete opaque, solid gray color, to a translucent (but less so than the “translucent” setting) one. Colors from the wallpaper still carry over.

Is this change intentional? If so, perhaps the opaque/translucent settings need some rewording?

Side-by-side comparasion: up: Plasma 5.27 (KDE Neon), down: Plasma 6 alpha. Both set to “opaque”

Not intentional. Probably a bug. But possibly one that’s already been fixed. “Opqaue” is working fine for me, FWIW.
