Make drag handle 100% height and remove js to manually set height.

## PROPOSAL

At first a 100% height handle seemed like a bad idea because of the expand/collapse sections on feature pages (since removed) and facet configuration.  Currently we've been setting a height then updating with javascript to fit the height of the containing element.  This causes certain issues when the height of the parent element changes after page load (e.g. edit-in-place).  I think having the drag handle be 100% of the height of collapsible areas is better than the oddities around setting the hight in javascript.

The only issue that I see is if we don't want the handle to be 100% height on expanded elements and there is an odd 1 pixel space on metadata fields that I can't seem to address (but perhaps isn't that big of a deal).  Screenshots of the current handles and the proposed handles as of this PR attached below.
