Font size doesnt override from custom typography

[tofesath]

Bug, feature request, or proposal:

override font size on the input element doesn´t work

What is the expected behavior?

I defined custom typography on the input element, where I want override this attributes:
font-size: 40px
line-height: 52px
font-weight: 400

What is the current behavior?

font size is not reflected on the input element

What are the steps to reproduce?

What is the use-case or motivation for changing an existing behavior?

I want override font size on the input element and in browser IE 11 writing text can't be floating

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Tested on Angular 5.0, Angular/Material 5.0.0-rc.2, all browsers and in IE with other line-height how is default 1.125 writing text is floating

I've submitted a fix @tofesath. Until it gets in you should be able to work around it by setting the font size on one of the form field's ancestors.
