This is true for all short pages, e.g. https://chromestatus.com/myfeatures/starred.

@KyleJu, you touched this last; do you think that's the right fix, or am I missing a better way to do it?

chromium-dashboard/client-src/elements/chromedash-app.js

Lines 45 to 49 in 1c39888

	#content {
	margin: 0;
	position: relative;
	min-height: 500px;
	}

seems to have the result of giving the sidebar at least 500px regardless of the main page content, but it should really have a height of 100%... Changing that div and this one to have a height: 100% property appears to fix the problem.

I think that will fix the issue. 500px might come from the minimum height from the content container, that shows the feature list. It is an issue when the list is empty.

Thanks for the fix!
