in 7.X, cannot specify font-size with em -- label disappears

So many dependency version conflicts… Ok, am attaching a simple app that shows the behavior. Note that the em sizes work fine for margins, but fail with font-size.

To see the label disappear, uncomment the ‘em’ font-size and comment out the ‘px’ one:

.largertext {
    font-size: 18px;
    //font-size: 1.4em;
    margin-top: 2em;
    margin-bottom: 2em;
}

Cheers,
Bobby
