Icons - Cannot Scroll to Top if Open Box in Scrollable View

[Ming Zhe Huang]

Please see the attached video. Also test case is attached.
This problem is similar with #13777.

• The open box is inserted as a sibling of mblScrollableViewContainer
• Moreover, the open box has "position:absolute" which means even if we pull it into mblScrollableViewContainer, it will still cause scroll problem.

[patch][ccla] patch to fix the issue by not using native scrollIntoView()

[Atsushi Ono]

This issue is caused by calling native scrollIntoView() inside scrollable. I have attached a patch to fix the issue as follows:

• Add a new scrollable#scrollIntoView(node) function, which adjusts scrollable's scroll position to scroll the specified node into the scrollable's displaying area.
• Use the new function above when IconItem is placed inside scrollable, otherwise use window.scrollBy instead of native scrollIntoView because it sometimes fails on some Android devices.
