Embedded iframe extending past parent div with overflow:hidden when tranform scaling is set

Reported by ba...@bluecore.com, Mar 22 2018 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36

Steps to reproduce the problem:
1. Go to https://jsfiddle.net/3p4qzyL1/3/ and run the fiddle
2. Depending on when it loads, you may need to click on the html pane to see the iframe extend the parent div

What is the expected behavior?
The iframe's overflow should be hidden outside of the parent div and so shouldn't extend beyond the height of the parent div.

What went wrong?
The iframe's content is overflowing outside of the parent div despite the overflow:hidden property being set.

Did this work before? Yes 64.0.3282

Adding ReleaseBlock-Stable for M-65 as this is a recent regression. Please feel free to remove it if it is not applicable.

Thanks.
