Originally reported at https://github.com/webcompat/web-bugs/issues/1973, this appears to be a regression. I tried bisecting, but got a weird final result: 23:31.46 LOG: MainThread Bisector INFO Last good revision: 5dbceb9638a01828296241661ff3c644d894f118 23:31.46 LOG: MainThread Bisector INFO First bad revision: c921afa9fc3e164ab52dc4564349a92e16663317 23:31.46 LOG: MainThread Bisector INFO Pushlog: https://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=5dbceb9638a01828296241661ff3c644d894f118&tochange=c921afa9fc3e164ab52dc4564349a92e16663317 STR: 1. visit mydealz.de 2. click on any of the dropdown arrow menus (top blue bar, or green bar) Expected: dropdown menu is displayed Actual: page navigation This one is kinda tricky, it seems like the top blue menu bar hits more easily than the green ones. Narrowed down to https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=cd345a81ac341641c52fdeb744ab2b80eccc0aa9&tochange=cc473fe5dc512c450634506f68cbacfb40a06a23 (and gave up) which have two bugs w/ touch related stuff: Bug 1174532 & Bug 1222234
Mike did the review for 1222234.
I think this is bug 1222234 comment 10 and the continued discussion – we increased the link target area and it makes it harder to click links on the page. bug 1233272 may be another manifestation to this. The two bugs (this one and bug 1233272) will like get duped to bug 1222234 once we figure out the best way to handle it.
Yeah, sounds like a regression from bug 1222234. We could back that out to fix this.

Michael, I made some tests without the code changes from bug 1222234, it doesn't fix totally the issues: - For the arrows in the green area, it works correctly (I get the vertical menu). - For the arrow in the blue area, it still doesn't work. To get the vertical menu for this blue arrow, I have to deactivate totally the "closest link" behavior (change the pref ui.mouse.radius.enabled to false). So this issue is more visible with bug 1222234, but it won't be totally fixed without the code changes from bug 1222234. Both issues (blue and green arrows) are not visible in version 44.0b2. Both issues are visible in 45.0a2. The blue arrow issue is strange: there are 2 links in the blue area (the home logo and the vertical menu) but it's another link below the blue area that is triggered (the ad area). Kats, do you know if there is another change in the "closest link" code explaining the blue arrow issue?
So the PositionedEventTargeting.* files are identical in aurora and beta. The difference in behaviour must be coming from somewhere else. I don't know of any other changes that would have affected this between 44 and 45.
Michael, my previous comment was based on the change of the preference values in about:config ; it doesn't fix the issue. I built a new apk with the back out of the code from bug 1222234, and now the issue is fixed. I'm going to investigate why the changes in about:config are not correctly applied and give the same results.
Backed out bug 1222234 – this should be fixed (see bug 1222234 comment 34).
