Looker watermark in embedded looks creates a scroll when zoomed out

It could be a new thing but I realised that regardless of my styling of iframes (100% width, 500px height) the vertical scroll always shows:

I did a bit of digging and realised that apart from my zoom out in Chrome (2 x CTRL -) removal of the watermark helps or adding some css.

Adding bottom:1px to #lk-embed-watermark-container would solve the issue.

With big screens I use zooming out very often, small tweak could be enough to cover all the cases
