Add Escaping of Content
See: https://github.com/westonruter/syntax-highlighting-code-block/pull/118
Humm. Somehow it seems that now doing <code>{escape(attributes.content)}</code> is double-escaping the content. It's causing block validation errors now in syntax-highlighting-code-block. Is the content now getting pre-escaped somehow?
Opened an issue to investigate: https://github.com/westonruter/syntax-highlighting-code-block/issues/201
It appears due to https://github.com/WordPress/gutenberg/pull/24689.
I've added what I believe is the required escaping logic in https://github.com/westonruter/syntax-highlighting-code-block/pull/200.
