Interesting.
I'm not going to do any more testing for now since I personally don't care - it was already disappeared by other Stylish rules I use that get rid of most of the stuff at the top in most browsers on most pages, and it doesn't "flyout" or do anything annoying for me - just sits there looking like a link.
Your rule looks similar to the first one I posted - my rule just takes out the that DIV element's parent LI element too -either one works to wipe out that area completely - but most would want to use
ebay.com##DIV[class="gh-menu gh--link__divider"]
without the www. prefix because using the www reduces the scope of the rule and causes it to not match
https://my.ebay.com/... or other pages on other eBay subdomains.
That approach can be used to tweak things slightly by using multiple rules with differing subdomain prefixes to create a sieve that removes it on some eBay pages but not others if desired to have that "Recently Viewed" "feature" be available some places, but is very limited due to scoping limitations of the adblocker rules.
(that's why I use Stylish CSS rules to hide things instead - it is surgical in it's ability to define the scope of rules using domains, URLS, URL-prefix, and RegEx, unlike the crude domain## or subdomain.domain## only scoping adblocker element hiding rules possess.)
