Shield textures in 1.14 and above are upside down in off hand!

I was making a resource pack that changes the look of the shield, I finished it and downloaded the file to MCPE and Xbox one. When I applied it and opened a world. I grabbed a shield from the creative inventory. The texture was shown completely fine when not in my off-hand, but in my off-hand, I noticed the texture was flipped upside down! I understand that it would be hard to notice if the texture was flipped upside down using the default resource pack, but the way I designed my shield in the RP made it so that it was as easy as squeezing lemons to notice the difference. Doesn’t seem right doesn’t it? Was this intentional? All I want is for this to be fixed.
