HLS pauses when switch resolution adaptively

[Sirius Wu]

I'm playing my modified version of android tutorial 5 to play an m3u8 link.
The version of gstreamer used is from the master branch.
After the buffering complete, I start to play, but after about 13 seconds
the player decides to change to a higher resolution, the buffering drop
immediately to less than 5%.

Why is the player not playing the old resolution until the buffering for
the new resolution is 100%? What can I do the fix the problem?

Appended file is the dot file of the player's pipeline.
