Can we get a bisect to figure out when this regressed? I think it might be fixed again - at least, I can't reproduce this in 62.0.3188.0.

Able to reproduce the issue on Windows 7, mac 10.12.6 & ubuntu 14.04 using latest Canary-62.0.3189.0.
Manual Bisect Info:

You are probably looking for a change made after 495358 (known good), but no later than 495359 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspect as some perf builds might get missing due to failure.

dschuyler@,Could you please take a look & reassign to the respective owner if it is not related to your change.

As it is a recent regression in M62, adding 'Release block Stable' label.

Thanks..!!

No repro on Linux - I think this is Mac only.

Err, more correctly, I suspect it's Mac and Chromeos. I've verified that it's not on Linux and expect it would also not repro on Windows (but haven't tested that).

commit 8aa2bf834647e8f2e5f97f8b0e9cc98cb727d44a
Author: Dave Schuyler <dschuyler@chromium.org>

[MD settings] settings-toggle-button default to settings-box styling

This CL changes the default settings-toggle-button style to be as a
.settings-box so that class="settings-box" need not be used on every
instance. Also changes remaining toggles rows to be fully clickable;
along with a formatting error on mac/chromeos with the font size 
drop-down.
