In #37495 we're discussing how to bring more coherence and consistency to the styles resulting from block customizations.

One of the "conclusions" of that discussion is that we should probably not consider a block that have differences in the wrapper level style attribute as invalid block.

So basically if the markup of the block is

<div style="something">content</div>

and the expected result is

<div style="something else">content</div>

The block should still be considered valid.

I'm creating this issue so we can track that and start exploring that change to the validation algorithm.
