Filter root element of tag cloud block


By default the tag-cloud block in the (Gutenberg) block-editor renders a root element as follows:

<p class="wp-block-tag-cloud">...</p>

This is the corresponding code what is renders the block:
https://github.com/WordPress/WordPress/blob/master/wp-includes/blocks/tag-cloud.php#L44

Filtering with pre_render_block doesn’t work.

Any idea how to filter this root element of this block?
