Task List Widget: Edit input not prefilled & focused

[pathseek3r]

Description:
When clicking the Edit button for a task, the input field that appears is empty and not focused. Users have to retype the task label from scratch.

Steps to Reproduce:

1. Click the Edit button for a task with an existing label.

2. Observe that the input field is empty and focus is not applied.

Expected Behavior:
The input field should be prefilled with the current task label and focused.

Root Cause (Code Snippet):

const editTask = () => {
    setIsEditing((prevValue) => {
      inputRef.current?.focus();
      if (inputRef.current) {
        inputRef.current.value = titleRef.current;
      }
      return !prevValue;
    });
  };

The issue occurs because the DOM element (inputRef.current) may not exist yet when setIsEditing toggles the state, causing focus and value assignment to fail.
