REGRESSION (WebKit2): Lookup bubble sized and positioned incorrectly (vertically off)
<rdar://problem/10294191> * SUMMARY In WebKit2 windows, the Lookup bubble does not line up exactly with the text. Its top is two pixels above where it should be, and the content is shifted up by two pixels. * NOTES Sometimes it’s only off by one, and sometimes the bubble height is wrong as well.
Created attachment 114842 [details] Use the WebCore::Font’s ascender height instead of the derived NSFont’s ascender.
Fixed in <http://trac.webkit.org/r100083>.
