Hello @vladislavyuzbekov, please stop trying to get additional attention through silly manipulation of the issue tracker. If you have something to add to the issue report, add a comment instead of repeatedly opening new issue reports. This is abuse of the issue trackers and you're going to force me to take action to stop you.

This is the fifth issue report for the exact same issue. Closing in favor of #2849.
