Set/get attributes in [JSUI] causes crash

This seems to be only affecting Max when running as an Apple Silicon Native app. Tested on Max 8.2.1.

Declaring an attribute in a [JSUI] with a setter and getter will cause a crash upon save.

This also happens when editing Max for Live devices in the latest Apple Silicon-compatible Live beta - it simply crashes if you try to open a Max for Live device containing a [JSUI] object with attribute setters and getters.

To reproduce, add a [JSUI] object and have it use the script below - try to save the patcher and it will crash.

var foo = 0
declareattribute("foo", "getfoo", "setfoo", 1)

function setfoo(x) 
{
    foo = x
}

function getfoo() 
{
     return foo
}
