React warning: a `div` tag was passed a numeric string value for CSS property

[dmarjenburgh]

This warning is given by React.

Warning: a div tag (owner: re_frisk_shell.core.debugger_shell) was passed a numeric string value for CSS property height (value: 250) which will be treated as a unitless number in a future version of React.

It's hinting at this line:
https://github.com/flexsurfer/re-frisk-shell/blob/master/src/re_frisk_shell/core.cljs#L228

Dependencies:

React 15.2.1
[reagent "0.6.0"]
[re-frisk "0.4.5"]

Shall I make a pull request?
