@proberge- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.


Thanks!

Thanks for the bug report. This is indeed related to https://chromium.googlesource.com/chromium/src/+/1b307437f07306488f4a72f45bec3e1217f0a99b. 

@dpapad looks like my change is causing trouble with this use case (clicking on the row creates a button whose height is greater than the text's height, causing the entire row to expand vertically). 

There's two settings-toggle-button which can contain "Relaunch" buttons:
1. "Use hardware acceleration" in chrome://settings/system
2. Metrics reporting in chrome://settings/privacy

The only way I can think of fixing the issue is by setting a -4px margin-top and margin-bottom on paper-buttons inside of settings-toggle-buttons. I'm not a fan of negative margins so this seems wrong; wdyt?

Found a different fix and sent https://chromium-review.googlesource.com/c/chromium/src/+/1135594 for review.

Thanks, I'll take a look shortly.

Chrome settings: adjust CSS to fix relayout of settings_toggle_button

In https://chromium-review.googlesource.com/c/chromium/src/+/1133300 I
changed how the padding of settings_toggle_button is calculated. This
caused some issues in cases where clicking the row creates a button
whose height is greater than the text's height, causing the entire row
to expand vertically.

This change applies the padding modifications to the text label instead
of the entire outerRow, preventing the padding from applying based on
the button's height instead of the text height.
