1085200 - [Text Selection] Distinguish difference between scroll-end and touch on non-editable place

Status: RESOLVED DUPLICATE of bug 1090008

Description

[(Inactive after June) George Duan [:gduan] [:喬智]]

In Gaia code, we hide bubble when I receive selectionchange event which has no mouseup and selectall in "reasons". So, in below two cases, 

1. when bubble has already showed and user try to scroll the content,

2. when bubble has already showed and user click other non-editable place

Gaia receive two similar events in above two cases which show hide the bubble after receiving that. 
However, for scrolling case, we actually hide the bubble before scroll, so I have no proper pre-condition to identify whether we should go to scrolling state or not.

We should prevent below failure steps:
1. launch a text_selection bubble
2. click on non-editable place
3. scroll the content   =>  bubble shows and the options are the same as step 1
(The bubble shows the same content, because we don't want to clear the cache of previous successful event for scrolling case.)

Hi Peter,

With latest gecko, I didn't see the selectionchange event before scroll start. Could you check again?

As offline discussed, the selectionchange event may come from b2g process.
