There is an issue in tabs height calculation that cause problem in close button position.
I explain this issue by examples.
Example One
Close button styles in above image.
One of above infobubble tabs size in chrome.
One of above infobubble tabs size in firebug.
Example Two
Close button styles in example two( above image ).
One of above infobubble tabs(example 2) size in firebug.
I logged this.tabHeight_ and both had same value 26.
As you can see in example two, close button position is not as same as close button position in example one because tab heights are different in examples.
