What happened?

We noticed when upgrading from Webdriverio version 8.29.1 to version 9.15.0, that "await driver.closeWindow()" suddenly throws following error "TypeError: Cannot read properties of undefined (reading 'length')" which fails our test.

Besides the error the window closes successfully. The "length" error could be ignored.

What is your expected behavior?

No response

How to reproduce the bug.

Open a mobile browser
execute "await driver.closeWindow();"

Relevant log output

TypeError: Cannot read properties of undefined (reading 'length')
