stepf does not skip splits with succesfull nodes

To reproduce:

Versions:

$ kompile --version test.k --backend haskell && kprove proof.k --haskell-backend-command 'kore-repl --version'
K version:    v5.3.60-0-gbf6c9cb9d0

Welcome to the Kore Repl! Use 'help' to get started.
...

test.k

module TEST
  imports BOOL
  imports INT

  syntax KItem ::= split(KItem) | "a" | "b"

  rule split(_:Int) => a
  rule split(K:KItem) => b ensures notBool isInt(K)

  rule a => .K
endmodule

proof.k

module PROOF
  imports TEST

  claim split(A:KItem) => .K requires isInt(A)
endmodule

Command line:

kompile --version test.k --backend haskell && kprove proof.k --haskell-backend-command 'kore-repl --version'

Repl:

step
stepf

Expected result: the current node should be '1'.
Actual result: the current node is '0'.

Reproduce the issue with test.k and proof.k using the listed kompile and kprove commands, then run step followed by stepf in the Kore REPL. Trace how stepf handles splits with successful nodes; done means the current node advances to 1 as expected.
