Fixes #4547: Name clash between ITooltip#getWidth, ITooltip#getHeight and Vanilla Widget methods leads to missing methods at runtime, since the implementing methods will be remapped to SRG names, while referees of the interface will try to call the renamed methods by their name in the interface, leading to an AbstractMethodError. (#4557)
