Previous Behavior
The default theme was not being set in Firefox. Firefox currently
SUPPORTS_ADOPTED_STYLESHEETS
but does notSUPPORTS_REGISTER_PROPERTY
. The CSSStylesheet being adopted on the first pass was an empty stylesheet. And because there were no tokens registered, styles weren't applied.New Behavior
This change will always update the stylesheet to the new theme and then adopt the stylesheet if it hasn't been adopted already.
