I don’t think there is a right answer here. Glyphs can have -ve right or left side bearings, so if the graphics context has no room on the either side then I think it is expected that the glyph would be truncated. This is not Arabic specific (e.g. italic f often have -ve right side bearing, in variable width fonts at least).
