Please add a TODO to revert these changes once we don't need to support options.

Should the hidden$ be on this div instead?

[xiaoyinh(OOO Sep 11-29), 2016/08/11 23:59:51]

Thanks Jacob. I could move it here. One thing is it will also hide the spacing
that comes with settings-checkbox which we might not care about.

[jdufault, 2016/08/12 21:45:35]

Okay, feel free to leave it wherever it visually looks best.

You can use the property directly instead of creating a helper function.

  hidden$="[[hideEnableScreenlock]]"

nit: newline instead of wrapping
