For the sake of completeness, this change was motivated by a StackOverflow question. I think the request in the question is quite reasonable.
This pull request supersedes #6040.
Support multiple tooltip and popover trigger methods
What's the reason for closing this? I though you'd be interested to merge?
@adrianlang it was closed when they deleted the 2.2.2-wip branch, and all of the requests to that branch got closed. I saw mark post in another issue to create a new pull request pointing to the master branch to try to get them into the next release which is what I ended up doing.. so yeah, I'd recommend sending the request again against the master branch. I'd also like to be able to use this feature so yeah, it would be awesome if you could do it again!
