lgtm, and thanks for fixing.

(what's the recommended way to avoid breaking things next time? should i
manually trigger a closure bot run if my CL has JS changes?)

eh, we're working on try bots for this.  that'd be the easiest.

in the mean time, locally doing:

  gyp --depth . third_party/closure_compiler/compiled_resources.gyp && ninja -C
out/Default

will probably work (may require a `sudo apt-get install gyp`).

it's not really that problematic to just fix after it breaks, swear ;)
