Forgot to mention where exactly fix this. It's in the getEditForm() method of the BlockAdmin.php class
so change this:
$blockGridField->setConfig(GridFieldConfig_BlockManager::create(true, true, false));
to this:
$blockGridField->setConfig(GridFieldConfig_BlockManager::create(true, true, true));

I stumbled upon this issue in the middle of a project after I created a couple of custom blocks :(
I spent 2 hours figuring out what happens, and found a solution.
There's a configuration class created for managing the blocks in a GridField here: /blocks/code/forms/GridfieldConfig_BlockManager.php
The 3rd parameter of the constructor is $canDelete = true, but when setting the GridField config in the getEditForm() method the constructor for GridfieldConfig_BlockManager is called with false for that argument:
$blockGridField->setConfig(GridFieldConfig_BlockManager::create(true, true, false));
Change it to $blockGridField->setConfig(GridFieldConfig_BlockManager::create(true, true, true));
and it will work.

I also tried to do this by using the Extension API but it's not working since the getEditForm()
is missing the following line before the return $form
statement:
$this->extend('updateEditForm', $form);
If that line would be there we shouldn't tamper with the core blocks source code - but I'm afraid there's no other way to make this work until it's not fixed.
