The bug
Back in 1.14 and before, in first person the item's on-model shadows changed accordingly to light (blocks that glow, the moon, the sun), but now the shadows don't change, not even with a really near light source.
The only item that I found that works as it should is the trident, the shadows change accordingly to the enviroment.
Update: The bug has been partially fixed in 19w45, but the lighting still behaves a little weirdly.
To reproduce
Be in first person mode
Pick any item and then hold it
Pick any source of light (the sun, the moon, a torch, etc)
Move your point of view in relation to the source of light.
Do this in 1.14.4 (or any previous version), and then in 19w42a

Yes, but it doesn't really specify that it's working in 3rd person.
I for example would not have been sure that this feature also exists in 3rd person in previous versions.
It working in 3rd confirms, that the responsible code is still present, even after all the rendering changes.
Title: Held item lighting in first person doesn't change accordingly in relation with light sources
In the bug description:
How to reproduce:
Be in first person mode
In those two instances it says that the bug is present only in first person
I don't know how to say it, I just can say that it doesn't feel right compared to how it behaved in 1.14.4 and before, maybe someone could attatch 2 videos showing the difference, because if I recorded a video I would have to compress it a lot to be able to attatch it to this report, and because of the compressing the issue would be difficult to notice.
The only way I can put it is that now the lighting is applied close to how it should be, but it is still off.
@unknown If you have a video that is too big in file size to be uploaded to the tracker directly, you can upload it elsewhere (e.g. as an unlisted video on youtube) and link it here.
Can confirm
