STR: 1. Long press on a word and wait for the copy-paste toolbox to show 2. Tap "copy" Expected: 1. Some kind of indication to tell the word is indeed copied Actual: 1. The toolbox simply disappears w/o any visual indication on whether or not I indeed hit the button or I accidentally hit the surrounding space.

After discussion with George, we decided to do it this way. The current implementation does the action when user finger-presses on a button, so there is no state changes of the button. First, we should fix this problem by doing the action when user finger-releases on the button. Then, when user taps (presses and then releases) a button, the button should stay at pressed state, and then fades out transition with the whole bubble, so that user can tell which button is tapped or he just taps outside of the bubble.
