How often does this happen? 


Additional Information:
In the current implementation, each fields' "changed" event will cause the
minicard rewrite the data, this is not efficient and bring some trouble to
other related operations. For eg. it difficult to tell when is the ending
of an editing action, hence can not say the input is valid or not.

This bug is raised when we investingate thit difficule #35194. Based on
Toshok's advice, I wrote a patch which just sync the data when the focus
leave the e-minicard-label. Will post it here for comments.
