Postgres: Block content doesn't refresh in rich text fields

[mhernesniemi]

Describe the Bug

Problem Description:

When editing text content inside a block that's within a Lexical rich text field and saving it, the admin UI doesn't update to reflect the changes. A browser refresh is required to see the updated content.

I tested it with Mongo and Postgres, and the problem seems to only appear on Postgres
