Both useState and signal seem to act badly on array after trimming!

Hi. This is with

  "dependencies": {
    ...
    "react": "npm:@preact/compat",
    "react-dom": "npm:@preact/compat",
    ...
  },
  "devDependencies": {
    "@preact/preset-vite": "^2.9.3",
    "@preact/signals": "^2.0.0",
    "@types/react": "^18.2.64",
    "@types/react-dom": "^18.2.21",
    "@typescript-eslint/eslint-plugin": "^7.1.1",
    "@typescript-eslint/parser": "^7.1.1",
    "preact": "^10.25.4",  
    ...
  }

I have something that looks like this.

function appState() {
  const logEntries = signal([]) // can be useState(), doesn't seem to matter
  const maxLogEntries = signal(100);
  ...
  return { logEntries, maxLogEntries }
}
const currAppState = appState();
...
function SomeElement() {
  const { logEntries, maxLogEntries } = currAppState;
  function updateLog(record:LOGRecord) {
    logEntries.value = [  ... logEntries.value, record ]
    // problem here!
    if (logEntries.value.length > maxLogEntries.value) {
       const delta = logEntries.value.length > maxLogEntries.value;
       logEntries.value = [ ... logEntries.value.slice(delta) ];
    }
    let Objs = []
    for (let i = 0; i < logEntries.value.length; ++i) {
       Objs.push((<LogElement entry={logEntries.value[i]}/>));
     }
    return (<div>{Objs}</div>);
  }

This works great as long as logEntries.value.length < maxLogEntries.value
but no amount of rejiggering seems to do the right thing if I decide to remove some entries off of the beginning of
logEntries.
I even tried copying the logEntries to a new array via [ ... logEntries.value ], slicing THAT array, and reassign THAT array back to logEntries.value, but no luck.
I also tried keeping an activity timer (via performance.now()) in a signal and then waiting for an idle moment before doing logEntries.value.slice(). I even put it into effect(()=>{ batch(()=> { ... }); }) or by itself in a batch(()=> { ... }) but no matter how I try removing some elements from the array I always get back the first maxLogEntries of LOGRecord. I.e. neither shift, nor slice(newBegin) seem to do the right thing for anything stored in a signal (or a useState() within SomeElement) for that matter...)

I can't believe this is a bug in preact state or preact signals. What am I doing wrong?

Thank you

Never mind. It was a bug in a nested element improperly caching stuff in its state :-(

Sorry for noise
