I own every plane from tier 4 - 10, as well as several tier 1 - 3 and several premium planes. One of the main reasons for me to use the hryunomod was to speed up hangar loading, but it sacrificed being able to look at my planes in 3D.
Thanks to this fix I no longer have to use the mod. The hangar is faster in 3D than is used to be with the mod enabled 2D image.
So a big thanks to WG for fixing this.
