Tooltip's position with the browser's border

[duy-tran]

Hello, I have a problem with the tooltip. When I hover on an area, a tooltip box appear on the top-left of that area. When the area is near the border of the browser, the tooltip box still appears at the same position, making some information hidden as shown below

Here's my demo site: http://quang-duy.16mb.com/demo3.htm

I want the tooltip to find a place to display the whole box, for example bottom left on the above situation.
Thank you for supporting.

Hello @duy-tran -

Thank you for reporting this, apologies for the delayed reply!

I have been able to reproduce this and yes, there are some issues with the way IM identifies the target position for tooltips. Marking this as a bug.
