Allowing persistent data with Matrix and other Fields in Listener

[Rfferrao87]

Is your feature request related to a problem? Please describe. When a Matrix and any other Field types share a Layout that's working under a Listener, the Matrix does not have its values persisted across updates to the targets defined elements, even when including it in the extraVars or the same targets variables.

Describe the solution you'd like Have the Matrix set columns/rows' values persist after updating some other Fields that share with it the same Layout and Listener.

Describe alternatives you've considered An alternative would be just keeping 2 separated Layouts — that is, 1 for the Matrix and 1 for the remaining Fields, nested within the Listener if need be —, but I feel like it would be more flexible this way.
