Hi Daniil,

Thanks for the patch.

Your patch should target the `master` branch. Also please add a
corresponding entry to the nearest open commitfest [1].

In this case you should add a test or two that demonstrate this. As
separate commits perhaps.

If you could also demonstrate that these tests improve code coverage
for instance that would be great.
