Change in code source kibana 7.13

Hello,
I have upgrade from kibana 7.5 to kibana 7.13.
and i want to change orientation of my dashboard kibana from right to left.
In kibana 7.5 it's easy, i change direction in commons.style.css and the changes are here but in kibana 7.13 not similor. Any change is not applicated.
Who can help please?

Any help!
who have a similar issue?

Would you mind opening an issue at https://github.com/elastic/kibana/issues/new?assignees=&labels=&template=Feature_request.md? Instead of hacking Kibana's CSS, maybe this can be a build-in advanced setting or something like that. Be sure to describe your use case.

thank you for your replay
