"<1>" label in snippet not transformed to a callout in `object` docs

[ivancea]

Describe the bug

The first code snippet within https://www.elastic.co/docs/reference/elasticsearch/mapping-reference/object has some <1/2/3>. The <1>, however, doesn't show as a "callout":

The source code comes from here: https://github.com/elastic/elasticsearch/blob/main/docs/reference/elasticsearch/mapping-reference/object.md?plain=1#L14

Expected behavior

It should be rendered in the same way as the others, and not be part of the snippet selection for copy-pasting.
