sort:wait time doesn't provide a logical sort order to tickets that have been responded to by an admin
We often submit admin responses to tickets without the issue being resolved, so the user is still "waiting" for a solution in a sense.
When you sort:wait, tickets with admin responses are at the bottom, sorted in no particular order.
While these tickets don't have a "wait" value, it is confusing that they are included in a seemingly random order.
Ways to deal with this:
Don't include tickets with an admin response in sort:wait. But if you use sort:wait order:asc, include tickets with admin responses in a logical order, ideally interspersed with tickets that are waiting, prioritized by message time.
Or we could include admin responded tickets in sort:wait, prioritized by message time, but this doesn't make sense based on a standard definition of "waiting".
