What problem does this address?

When selecting multiple blocks from within the list view in the site editor and hitting delete, it doesn't delete those blocks.

Another block deleting issue I've run into is that the delete actions seems to only work in certain scenarios. The video below shows selecting a paragraph block below the post content block and hitting delete just selects post content block instead.

It might be worth looking at both issues to see if there is a singular solution.

What is your proposed solution?

Selecting a block from list view and hitting delete should always delete the selected block.
