6.1.0rc1 - matrixify not applying to query B in Mixed Chart

[fin-gal]

Bug description

Hello,

I am using Apache Superset 6.1.0rc1

I am using Mixed chart along with the matrixify feature activated with MATRIXIFY flag.
The dimension used to enable the vertical layout of matrixify only seems to apply to the data in Query A but not the data in query B.
