Morph target curves are not played back on additional meshes (sharing same skeleton)

Morph target curves are not played back on additional meshes (sharing same skeleton). Meaning if I preview facial animation on a main preview mesh (body) with the head as an additional mesh the morph targets do not have any effect.

It does work if I use the head mesh as the preview mesh (removing it from additional meshes). However I think curves should affect all preview meshes, even the ones in Additional Meshes.

This problem happen too in 4.18 -.- My team is stucked with this from 4.17

We are experiencing the same issue
