Should details tags work in comments?

+1
−2

In a post a <details> tag can be used to hide information until a user chooses to click on it, useful for spoilers or puzzle solutions.

For example, the following raw text:

<details>
<summary>
Click to see the answer
</summary>
The answer is "Ask why 5 times"
</details>

is rendered as:

Click to see the answer The answer is "Ask why 5 times"

Currently comments support some HTML, such as bold, italics and supercript. Would it be useful for comments to also support hidden information with the <details> tag?

What would be the use case? (2 comments)

Even if it didn't actively encourage misuse of the site, time spent on a feature like this would be far better used elsewhere.

<details> tags are already sufficient to implement a "spoiler" within an answer. If for some reason it were necessary to mark comment content as a spoiler - for example, discussing a candidate puzzle solution - keep in mind that comment threads are already hidden by default: they're collapsed behind the thread title. The appropriate course of action is to use a separate comment thread and title it in a way that gives suitable warning. Content that needs to be marked this way shouldn't be dropped into an existing comment thread anyway.

Regarding debugging: comments have a much shorter character limit anyway. A long log simply isn't going to fit into 1000 characters, so it couldn't be posted in a comment. Comments that fit the line limit aren't going to need collapsing for space unless they're abusing line breaks (which is probably flaggable anyway).

Don't rely on comment threads being hidden by default. (2 comments)

This answer (at least in the first revision) coincidentally is 995 characters long, so it (less the footer) gives an indication of how much screen space a "full-length" comment might be expected to take up. To me it hardly seems worth collapsing.
