[FIX] blockdom: fix crash when class object key has leading spaces

Browse Source 
Previously, having a leading or trailing space caused
HTMLElement.classList.add to be called with an empty string (because we
are splitting on whitespace), which is not allowed and caused a crash.
This commit fixes that by trimming the keys of the class object in the
same way that we already do it for class strings.
