Update block programmatically?

[manake]

Is there a way to update a block programmatically?

This is related to this problem #12333

I want to trigger "remove data-align="full"" on page load to fix that bug.

If someone could post a list of all methods/operations that we can do (if any) programmatically that would be useful to have.

So you want to update the block markup in PHP, right? You could use the render_block filter to remove data-align="full" for a specific block.

Ok, I was thinking incorrectly about this issue. I was trying to disable wide alignments before the block's HTML is generated. That's not the right way of doing this. Never mind.

render_block is a good solution. Thank you.
