Unstable_TrapFocus.js:84 Uncaught RangeError: Maximum call stack size exceeded.

This error occurs when a function calls itself repeatedly until the call stack reaches its maximum limit. The most common cause of this error is a recursive function that doesn't have a proper exit condition, causing it to call itself indefinitely.

In the case of the Unstable_TrapFocus.js script, the error is likely caused by a recursive function that's being called repeatedly, causing the call stack to overflow. To fix the issue, you'll need to identify the recursive function and add an exit condition that prevents it from calling itself indefinitely.

One way to do this is to use a debugger to step through the code and identify the function that's causing the error. Once you've identified the function, you can add a conditional statement that checks if the exit condition has been met before calling the function again.

For example, if the function is supposed to iterate over an array and perform some action on each item, you can add a check that stops the iteration once the end of the array is reached:

function myRecursiveFunction(array, index) {
  if (index >= array.length) {
    return; // exit condition
  }
  
  // perform action on array[index]
  
  myRecursiveFunction(array, index + 1); // call function again with incremented index
}

By adding an exit condition to your recursive function, you can prevent it from calling itself indefinitely and avoid the "Maximum call stack size exceeded" error.
