GJSON / gjq doesn't appear to work with query paths

[Honest-Objections]

As per the docs, the following works as expected:

jira view JIRAT-1234 --gjq 'fields.issuelinks.#.id'
# ["123456"]

A trivial example, which you would expect to output 123456 returns nothing but a new line

jira view JIRAT-1234 --gjq 'fields.issuelinks.#(id=="123456").id'

This would be crazy powerful! I hope someone can tell me what I'm doing wrong, but I have tried a lot of variations
