MUI and MUIA_String_EditHook - no IEvent!

Hi,

I just noticed what must be a (recent) bug in MUI on OS4:
I have added a MUIA_String_EditHook and it is supposed to be called with a number of field, like IEvent, but with MUI it is not.
On ReAction it works fine, and I'm 100% sure it must have worked before because I implemented the code 15 years ago for MUI and RA in parallel.

I have a normal StringObject, like this:

Here is the content of the SGWork in the hook on MUI vs. RA on OS4:
//muios4 reqwinfunc:
StringInfo=0x513f6b94, WorkBuffer=0x4d6d1018, PrevBuffer=0x49897d60,
Modes=16,
IEvent=0,
Code=98, BufferPos=1, NumChars=1, Actions=17, LongInt=0,
GadgetInfo=0, EditOp=8

//ra-os4 reqwinfunc:
StringInfo=0x4d074a34, WorkBuffer=0x54e599b8, PrevBuffer=0x552959b8,
Modes=0,
IEvent=0x6f0e7670,
Code=98, BufferPos=1, NumChars=1, Actions=17, LongInt=0,
GadgetInfo=0x6f295c16, EditOp=8

As you can see, the MUI hook is missing IEvent and GadgetInfo.

The whole point of the hook is to read the up/down arrow keys and navigate a list (string history).
But the hook isn't even called for rawkeys on MUI, so becomes useless even if I could work around the missing IEvent.

This must have worked before, otherwise I wouldn't have implemented it for MUI, but only for RA where it works fine.
