I'm probably missing something very obvious but it seems like [`/users/{ids}/answers`](https://api.stackexchange.com/docs/answers-on-users) forgets to include the `tags` badge in the resulting [answer object](https://api.stackexchange.com/docs/types/answer):

> tags (2.1) an array of strings

Nowhere does this mention that it *may be absent*. So, I gather that it must be included with every query that I make to it. And yes, I'm using the appropriate filter.

Interesting behavior: Sometimes, I do see the item, but not always.

[Here's a demo of the bug][1].
  
I read [somewhere](https://api.stackexchange.com/docs/absent-fields) that fields with *null* values are excluded, but I always understood that to mean fields marked with *may be absent* only.

So, is this a bug?

Editor's note:  This appears to be *similar*, but not the same as the bug: https://stackapps.com/questions/7213/the-answer-object-returns-an-empty-array-for-tags.  The workaround there does not work in this bug's case.
