text-overflow on flexbox should have no effect

Since flexbox doesn't have any direct inline children, text-overflow
should have no effect. There is code that checks for the parent's
text-overflow style, but that should be limited to blocks where we
created anon blocks because of mixed inlines and blocks -- grid and flex
should not be affected.
