Expected Behavior

All boss bars should be rendered correctly.

Actual Behavior

Only the first boss bar is rendered correctly; the second one seems to be having issues with its alpha.

Hwyla is apparently also a victim of this issue.

Reproduction Steps

1. /bossbar add test1 "First Test"
2. /bossbar set minecraft:test1 players @a
3. /bossbar add test2 "Second Test"
4. /bossbar set minecraft:test2 style notched_6 (note: it has to be a "notched" style - I think this is the part that's messing up)
5. /bossbar set minecraft:test2 players @a

Just tested with 1df506f, this issue still occurs.

Was this fixed?

This is a vanilla bug (apparently I didn't state that before closing). Ended up fixing it myself.
