This is also notably an issue with sbyte, short, and ushort. It is also, unfortunately, a breaking change and will need a bar check.

The intent had indeed been to correctly mask, which is being done in other operations but was missed for these ones.

OK. I will wait for a conclusion before further action.
(I set the PR as draft just because I recognized the test should be put in ByteTests.GenericMath.cs)

@skyoxZ, just wanted to let you know that this is still on my radar.

I need to create a breaking change doc for this prior to getting it merged, which I should get to in the next couple days.
