Some elements cannot be flex containers

[mnzaki]

Angular Material keeps complaining about this:

Markup '<fieldset flex></fieldset>' may not work as expected in IE Browsers. Consult 
'https://github.com/philipwalton/flexbugs#9-some-html-elements-cant-be-flex-containers' for details.

Markup '<md-button flex></md-button>' may not work as expected in IE Browsers. Consult 
'https://github.com/philipwalton/flexbugs#9-some-html-elements-cant-be-flex-containers' for details.

Some culprits include fieldset.html and submit.html which have flex on a <fieldset> and <md-button> respectively.
