Re: [whatwg/dom] May return the same HTMLCollection object (#706)

If I use a 10s timeout instead of 1s I get `undefined` in Firefox. 

For what it's worth, in Firefox you can set the "javascript.options.mem.log" preference to true to get logging in the view shown under "Tools > Web Developer > Browser Console".  In this case, I see no GC activity on that page within the 1s timeout, which is why you see the  results you see.   I'm pretty sure we deprioritize GC activity during and right after pageload to improve responsiveness in Gecko...
