Order of variables causing undefined in IE11 scripts

[dlabaj]

Order of some of the variables is causing undefined to be created by IE11 script when used as described here:

https://github.com/patternfly/patternfly-next/wiki/IE11-Support

The variables that are being created as undefined are the following:

.pf-c-form__actions {
display: flex;
flex-wrap: wrap;
margin-top: undefined;
margin-right: undefined;
margin-bottom: undefined;
margin-left: undefined;
overflow: hidden; }

.pf-c-login__main-footer-links {
display: flex;
flex-wrap: wrap;
justify-content: center;
padding: 0.5rem 4rem 2rem 4rem;
margin-bottom: undefined; }

.pf-c-wizard__toggle {
position: relative;
z-index: 200;
display: flex;
justify-content: space-between;
width: 100%;
padding: 1.5rem 1rem 1.5rem calc(1rem + undefined + 0.5rem);

.pf-c-wizard__toggle-list {
position: relative;
display: flex;
flex-wrap: wrap;
align-items: baseline;
margin-right: 0.5rem;
margin-bottom: undefined;
list-style: none; }
