We can't fix this ourselves.

Did you make a typo? Removing the top margin won't fix left-right issues.

Sorry yes typo! Fixing now. The left margin is the problem here from what I can see.

A better fix would probably have been to display the globe logo that somehow went missing during the conversion to the 25th branding.

.mw-logo-icon {
	display: inline;
}
