Unwanted new tab opens every time I click on a link which is not expected

H all,

I have an issue with my automation (selenium-webdriver). Every time I click on a link, that link would open in a new tab(this is not expected, and links do not have _blank attr. set to them), my automation fails cause it stays on the first tab.

I've tried setting up a new automation env on a new PC - same result. I've tried releasing Ctrl key using :controlKeyUp - same result

This issue happened during bug-fixes merge from v1 to v2 of my product.

P.S. on a version with older code automation works fine with no issues. P.P.S. This issue is not reproducible manually.

Thanks!
