After a little more research I found that the version of cas.css being used 
by default is being provided by the cas-server-webapp-tomcat.war file from 
the Maven repository.  I don't really understand what code base this .war 
file is generated from since the github repo doesn't have this cas.css file 
or the directory structure for it (although in earlier versions of CAS it 
did exist).

So at the moment I can fix the apereo theme cas.css but not the 
cas-theme-default cas.css so that these pages display properly in IE 11.

Again, if anyone has an idea on where the cas-theme-default cas.css can be 
modified in a repo I can also submit a change for that.
