VSCode内でGNU-RXビルドしたプログラムのSimulatorデバックでタイマー割り込みできない

無茶苦茶久しぶりのLunaJamと申します。

e2studioでGNU-RXでのビルドとSimulatorデバックでICUとCMTを有効にすればタイマー割り込みが確認できますがVSCode+Renesasプラグインの場合ではどうやってもタイマー割り込みが発生しません。タイマー割り込み以外は普通にデバックできます。
こういう仕様なのか設定の問題なのかどうなんでしょうか。

起動時に引数が表示されるのですが規定値の後に設定値が追記される感じで認識されていないように見えます。

launch.jsonはこんな感じ
