[🐛 Bug]: BiDi BrowserContext fails to open new tabs in Chrome #15860
Description
Description
When attempting to use BiDi BrowserContext to run multiple tests in parallel with a single WebDriver instance, the expected behavior is for each test to run in its own context (tab) within the same browser window. This works correctly when using Firefox — multiple tests run concurrently in isolated contexts, all within a single browser instance.
However, switching to Chrome (using the same code) results in each test launching a completely separate browser window.
Steps to Reproduce:
Check added code
Expected Behavior:
All tests should run in separate BrowserContexts within a single Chrome browser window.
Actual Behavior:
Each test launches its own Chrome window instead of sharing a single instance.
Environment:
Browser: Chrome 137.0.7151.55 (Official Build) (64-bit)
Selenium version: 4.33.0
Operating System: Linux Mint 21.3 Cinnamon
