Chrome Version: 
OS: Linux (tested)

What steps will reproduce the problem?
Repro at https://jsfiddle.net/jp04kp4h/1/

What is the expected result?
After setting the height of both the video and the containing div, both should be the value entered (100px by default).

What happens instead?
The scrollHeight of the container element is 4px larger than it should be.

Setting display:block on the video fixes the problem, but it doesn't repro with any other element I tried, and gives the correct value in Firefox, so I think this is a bug.
