I believe we don't always have the latest version of the game.
They should've been fixed it in their closed devbuild.

Alright, my bad, you're right - unlikely it was caused by being fainted, because you wasn't fainted.

This issue has been already fixed http://phabricator.legendsofequestria.com/T467

I believe this bug was already submitted http://phabricator.legendsofequestria.com/T241

Wow did not know it is possible with trees too! :)
Doing side flips near obstacles seems to lead to similiar results http://phabricator.legendsofequestria.com/T98

Not dealing any damage probably caused by you being fainted (check the chat).
There is a huge delay between being fainted on server and an appearing of respawn dialogue.

Was bothered by this issue as well.

I can confirm that I had to talk with Marvel twice to complete a flag about talking with Marvel.

Also bunnies can walk upon the water surface too:

It is possible to walk and fight after the chat said "You got fainted" and until you get a menu with Respawn Button.
The delay between these two events may be significant, for me it usually takes a few minutes!
Sometimes I get fainted while I already left the battle and standing in a safe place with no enemies around.
