[BUG] trailing zero width whitespace fails toHaveText

[jtgober]

Context:

• Playwright Version: 1.16.3
• Operating System: Windows
• Node.js version: 14.18.1
• Browser: chromium
• Extra: n/a

const { test, expect } = require('@playwright/test');

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  await page.locator('text=Get started').click();
  await expect(page.locator('#installation')).toHaveText("Installation​");
});

The issue has to do with the expect statement when this is ran, it fails the test. However, see the expected v.s. the received

Error: expect(received).toHaveText(expected)

Expected string: "Installation"
Received string: "Installation​"

What is bizarre, is if I were to copy/paste the Received string: "Installation​" into the toHaveText field, it comes back successful, although there are no changes.

Looks like a real bug. There is a trailing zero width space in the end of the actual string. toHaveText should have been forgiving and should have accepted it as a proper value.
