Bitstream mismatch related to IntraBC

What version / commit were you testing with?

c2f337b7

What steps will reproduce the problem?

1. Build with bitstream debug tool

   cmake ../avm -DENABLE_DOCS=0 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCONFIG_BITSTREAM_DEBUG=1 -DENABLE_ASSERTS=1 && make

2. Run this encode (CTCv7 AI command, with some frames skipped for faster rerpro):

   ./aomenc b2_scc/MissionControlClip1_1920x1080_60fps_10bit_420_0450_0579.y4m  --tile-columns=0 --threads=1 --kf-min-dist=0 --kf-max-dist=0 --use-fixed-qp-offsets=1 --tune-content=screen  --test-decode=warn --cpu-used=0 --passes=1 --end-usage=q --deltaq-mode=0 --enable-tpl-model=0 --enable-keyframe-filtering=0 --obu --psnr -v  --qp=210 --skip=0 --limit=17 -o /tmp/out.obu --skip=14

What is the expected output?

Success
