What is the new behavior?
Chrome:

Firefox:

• Replaces the "Change Text Size" icon with one from material design icons
• Improves the positioning of the "Change Text Color" icon
• Makes sure the font color is not inherited by material design container
  • This increases contrast and therefore makes bold text more distinguishable (at least in the default case of black font color)
  • Makes sure the text in the editor looks more like the final result in the form

Does this PR introduce a breaking change? (check one with "x")

• Yes
• No

Other information:

• The linked JIRA ticket also asks to remove the logging to console of the "Change Font Size" plugin. However this is coming from the external plugin (see https://github.com/quanzo/change-font-size/blob/master/src/index.js#L87).
