[BUG] Wrong behaviour for Playwright grep regex

[EldoradoEU]

System info

• Playwright Version: [v1.36.1]
• Operating System: Windows 10
• Browser: MS Edge
• Other info:

I have 3 test cases with names:
Testt, Test, TTest

command:
npx playwright test --grep "^Test$" should execute only test case "Test"

Expected

Playwright should run single test "Test"

Actual

Playwright run "TTest" and "Test" it looks like problem with sign "^" for --grep regex

Playwright matches against the titlePath() not only the test title. We describe it here but not here and here.

We should make it more clear or fix it.
