Nit: It might be good to name this something more specific like
#title-left-content.

(There are probably several things in this element which are the 'left content')

Done.

I moved "last-update-time" out of "title-text" so that only the device name get
truncated, which I think looks better.

           <span id="last-update-time">[[lastUpdateTime]]</span>
