It is unclear if LogicalFontInstance::GetGlyphBoundRect can be called for both normal and rotated variants of the same glyph in the same font. If yes, then the normal and vertical variants must be cached separately, or possibly vertical variant can be not cached, but always calculated. This problem already existed before, so this change doesn't introduce a new issue.
