chrome 35.0.1916.114, ABP 1.8.3, easylist

How to reproduce

go to
​http://www.learnkeeper.com/#dictionary/fr/en/

Try to change the lang by clicking on the dropdown btn "fr-->en"
==> does not work

if I remove easylist (and add for example only easyprivacy) it works
if I use only fanboy's social list ==> does not work

if I use chrome 37 + ABP 1.8.3 ==> it works

in firefox no issues
ABP does not block anything in that page

This is being caused by some element hiding rule. Not related to Shadow DOM however, the same issue still occurs even if Shadow DOM isn't used.

It seems that the following selectors are causing it among others:

a[id^="mg_add"]
div[id^="MarketGid"]

Removing all selectors applying to id attribute fixes the issue. This is most definitely a Chrome bug. Unfortunately, this website being a huge block of minified JavaScript doesn't really make it easy to minimize the testcase.

Managed to reproduce this in a local file (wasn't quite trivial, the website apparently doesn't work quite the same if its network requests fail). The following style rule is sufficient to reproduce this: foo[id] {}. In other words, any selector touching id attribute will do, the actual CSS properties associated with it are irrelevant.

probably (if chrome bug) it was solved in chrome 37 (I didn't try chrome 36 beta)

Local copy of the site with the issue reproducible without ABP

Yes, this isn't reproducible in Chrome 37. I attached a ZIP archive with the local copy of that webpage - it contains a foo[id] {} style rule which makes this reproducible without Adblock Plus. I think that's as far as we will go: investing effort into reducing a GWT-based website shouldn't be worth it given that the bug is already fixed. If anything, we can try determining when exactly this was fixed, probably not worth the effort either however. And implementing some hack to drop id-based style rules on that website isn't worth it either, disabling Adblock Plus on this website is an easy work-around until Chrome 37 becomes stable (no ads there).

Resolving as invalid because this isn't our bug.
