Tooltip outside bug

[Basts]

When tooltip.outside is set to true and chart has more than one series with different types (checked at column & line and column & spline) occurs tooltip bug - tooltip displays without right and bottom border and without a pointer. What I noticed:

• it happens in greater than 5 version (in 5 it works fine),
• the bug doesn't occur always, so it's needy to refresh the browser,

The bug is connected with the post from the forum

If you are happy with how version 5 works then you could just disable the option, because it was added in v6.1.1.
