`@Desc` does not match FieldInsnNodes

[Geolykt]

Initially reported on discord last year (https://discord.com/channels/142425412096491520/626802111455297538/1303113014039547975), but got no response so I'll post it here again.

The issue in question: stianloader/Micromixin@87b91ec
InjectionPointTest.FieldInjectDescInt passes correctly, but InjectionPointTest.FieldInjectDescObject fails. Culprit seems to be

Mixin/src/main/java/org/spongepowered/asm/mixin/injection/selectors/dynamic/DynamicSelectorDesc.java

Line 513 in 4053421

if (!compareWithDesc.equals(desc)) {

- compareWithDesc being java/lang/Object while desc is Ljava/lang/Object;

Is this a feature or a bug? If it is the former, then what is the rationale behind this behaviour?
