Can't create a table block programatically

The CMS Questions

Okay I found the issue: I have call toArray() on the blocks

site()->createChild([
  'slug' => 'blocks-test',
  'template' => 'blocks-test',
  'content' => ['text' => $blocks->toArray()]
])->publish();

I found the solution here: Create custom blocks programmatically - #12 by texnixe. But in this case it was a custom block that didn’t get saved, but table is a built-in block.

Would be great if this behavior could be fixed because now it is really inconsistent. Maybe the page update/create methods could call toArray() by default if a Blocks instance is passed?
