fix(material-experimental/mdc-tabs): support backgroundColor on nav bar (#21746)

crisbeto · web-flow · commit da5e2eb390d7 · 2021-02-05T17:59:33.000+08:00
Fixes that the MDC-based `mat-tab-nav-bar` doesn't support a `backgroundColor`. This is
something we support on the non-MDC version, but it didn't make it into the MDC one for
some reason.
