I am trying to see and show whether a comment on question/answer is flagged by the authenticated user.

 1. But whenever I use [/questions/{ids}][1], `can_flag` is `true` irregardless of whether the user (me) can actually flag the comment.
 2. When I use [/comments/{ids}][2], I get the correct status.
 3. *Editors note*: additional/updated/different info in the answer below, but this still looks like a set of bugs.


**Example:** 

 1. For [*The API Sandbox* question on Meta Stack Exchange][3]:

 2. In [this answer there (Id 54725)][4], **I flagged** the (now deleted) [comment with ID 764560][5] (Link now works only for SE devs and MetaSE moderators). 

 2. But the `/questions/{ids}` route shows `can_flag: true`, which is **incorrect**:

  [![questions route shows incorrect can_flag][6]][6]

 2. However, using `/comments/{ids}` I get `can_flag: false`, which is **correct**:

  [![comments route shows correct can_flag for flagged comment][7]][7]

  <br>
 2.  I also tried `/comments/{ids}` **for an unflagged comment** ([comment ID:396655][8]). It gives`can_flag: true`, which is **correct**:

  [![comments route shows correct can_flag for unflagged comment][9]][9]
 

Why is there an inconsistency? **This looks like a bug.**


----------
Note: I did (re)check `/questions/{ids}` 30 minutes after flagging the comment.  So this does not seem to be a time-delay/caching issue.
