2022.1 Unnecessary whitespace inconsistency

Unnecessary whitespace outside of the namespace declaration is no longer highlighted (where I have the inspection "Unnecessary whitespace at the end of line" set to Error). This includes at the end of using statements (after some testing I find that it is only on the last using statement (the one before the namespace declaration)):

using System;_________ ok
using System.Linq;__________ missed
_______ missed
namespace MyNamespace {_____ ok
_______ ok
}________ missed
__________ missed

All of them are still removed on save (if that setting is enabled).

Another issue is that if I delete the last piece of whitespace on a line, the editor will now force delete the new-line with it. This means that I can't manually make a line empty (at least by pressing backspace).

namespace MyNamespace {
}
_*

* is cursor. pressing backspace once results in:

namespace MyNamespace {
}*
