Wrong context set when using within

Bắt đầu bằng cách lần theo hàm _getContext và phần triển khai của within, sau đó chạy ví dụ modal được cung cấp cùng với waitForEnabled. Kiểm tra hành vi liên quan của waitForDisabled, waitNumberOfVisibleElements, waitForValue và waitForText. Hoàn tất khi within('.modal-dialog') sử dụng đúng context của page hoặc frame và các helper này hoạt động bên trong block mà không có lỗi context.

Description

After updating to CodeceptJS version 3.6.10 (also occurring in 3.7.0), we noticed that the within functionality no longer works correctly when used with a selector like .modal-dialog. Instead of setting the context to a page or frame object, it sets it to a locator object, which causes an error when trying to execute certain functions.

The error encountered:

context.waitForFunction is not a function

This error occurred in the waitForEnabled function, which expects context to be a page object, but instead it is passed as a locator because of the changes introduced with: #4557
Other helper functions that we found that produce the same error: waitForDisabled, waitNumberOfVisibleElements, waitForValue.
We also observed other functions like waitForText not working correctly inside within (e.g. not finding text inside the within context although it was obviously there).
Specifically this line in the _getContext function breaks this use case, since it now returns this.context even if it is a locator object:

  async _getContext() {
    if ((this.context && this.context.constructor.name === 'FrameLocator') || this.context) {
      return this.context
    }
...

Everything worked fine again after reverting the changes that were introduced by this commit.

Steps to Reproduce

1. Use the within function with a selector such as .modal-dialog.
2. Attempt to run a command inside the within block, like waitForEnabled.
3. Observe the error message.

Example test case:

Feature('Modal Test');

Scenario('Test modal within', async ({ I }) => {
  I.amOnPage('https://example.com'); 
  I.click('.open-modal');
  within('.modal-dialog', async () => {
   I.waitForEnabled('.button')
  });
});
