[Bug]: Error stack traces are truncated when using steps inside POM

[ChernyshovDmitriy]

Version

1.59.1

Steps to reproduce

1. Create project by npm init playwright@latest
2. Paste this content of example.spec.ts

import { test } from '@playwright/test';
import { TestModel } from '../test.model';

test('has title', async ({ page }) => {
  await page.goto('https://playwright.dev/');

  const model = new TestModel(page)

  await model.shouldBeCorrect();
});

3. Create simple test.model.ts which just contains several methods, some of them calls Promise.all and uses test.step functionality

import test, { expect, Locator, Page } from "@playwright/test";

export class TestModel {
    readonly body: Locator
    constructor(page: Page) {
        this.body = page.locator('body')
    }

    async shouldBeValidColor(): Promise<void> {
        await test.step('Check color', async () => {
            await expect(this.body).toHaveCSS('color', 'fffffff');
        });
    }

    async shouldBeCorrect(): Promise<void> {
        await test.step('Check all', async () => {
            await Promise.all([
                this.shouldBeValidColor(),
                this.shouldBeValidColor(),
            ])
        });
    }
}

4. Try to run test from example.spec.ts

Expected behavior

I expect and previous versions of PW (1.58.0 for example) shows something like this
I want to see whole stack trace includes shouldBeValidColor and shouldBeCorrect methods and line from example.spec.ts where method was called

    at test.model.ts:11:37
    at TestModel.shouldBeValidColor (test.model.ts:10:20)
    at test.model.ts:18:22
    at TestModel.shouldBeCorrect (test.model.ts:16:20)
    at tests/example.spec.ts:9:15

Actual behavior

Error trace was truncated to 3 lines
We don't see that TestModel.shouldBeCorrect was called

    at test2.model.ts:11:37
    at TestModel.shouldBeValidColor (test2.model.ts:10:9)
    at test2.model.ts:17:13
