search icon breaks with Floats style in 3.0 theme

Hello Team,

This is seen with latest available alpha.3 theme as well (I had initially observed this with alpha.2)

The search icon in the primary navigation bar doesn’t wok with following combination
Floats + Primary nav aligned to Center + Enable search in navigation bar

With this setting if you click on search icon, it will disappear and we also don’t see close icon. But when I change the navigation alignment to left then the search icon works just fine

This is only with Floats, with FlexBox there are no issues

Regards
Deepak
