Leafref and cli-compact-sytax behavior

list a {
tailf:cli-compact-syntax;
key a1;
leaf a1 {
type string;
}
container a2 {
leaf a3 {
type uint32;
}
}
}

leaf b {
leafref {
path “…/…/a/a1”;
}
}

Here this leafref works perfectly for ‘/a[a1=“xyz”]’ but fails for an extended version of the same list entry like “/a[a1 =“xyz”]/a2/a3”.

Perhaps I am missing something here. Should the leafref path be more definitive to make it work for both the cases?

Can you describe the expected behaviour?
