"Synchronize all translations" doesn't work in profiler

Hi,

"Synchronize all translations" button doesn't work in profiler.

I get the following JS error when I click:
symfonyProfiler.js:43 Uncaught TypeError: Cannot set property 'innerHTML' of undefined at syncAll (symfonyProfiler.js:43) at HTMLAnchorElement.onclick (f8c6e1?panel=translation:1994)

For information I'm using Symfony 3.4.2 and chrome 63
