Font size and code window adjustments not working when connecting external monitor

[jharaldson]

Start Field on a Macbook Pro without an external monitor connected.
Connect an external monitor and mirror the display.
The font size will become very large.
Adjust the font size by using _.textEditor.injectCSS(".CodeMirror {font-size:8px;}")

Issue 1:
Enter presentation mode.
Font size is not adjusted.

Issue 2:
Ctrl+space click on a box and choose "rename".
It is not possible to see the cursor and what is being typed.

Issue 3:
When switching back to the Macbook monitor it seems that Field believes the code window width is not adjusting to the code window and the lines are not breaking.
