[4.x]: Matrix & NEO Block Validation fails when autosaveDrafts is deactivated

[maxstrebel]

What happened?

Description

Because of regular Mutex Lock /saving problems we had to deactivate autosaveDrafts. Since some time (we cannot pin it down unfortunately) we see problems with Matrix and NEO Block validation and in general when saving entries.

In this very case, saving will first show a notice it can't save but no validation message at the block in question, when a required field is missing. Second save, with the missing block, will then save – but will delete the block. It won't validate (as it does when autosaveDrafts is active).

Steps to reproduce

1. Set "autosaveDrafts" => false in general.php.
2. Create a new matrix field
3. Add a required text field to matrix
4. Create a new entry
5. Add a matrix (or NEO) block and the created, required text field but leave the content empty
6. See toast with info that entry could not be created, but no validation on the field
7. Save again
8. Will now remove the empty block and show success

Expected behavior

Blocks should validate, no matter if autosaveDrafts is deactivated.

Actual behavior

Block will not show validation message. Block will vanish on second save.
