This started to fail frequently after bug 1393326 landed. Geoff, can you take a look, please?
Flags: needinfo?(gbrown)
Bug 1393326 started running Android mochitests by-manifest, so this test is probably running in a "fresher" browser instance now. It may have been inadvertently relying on state set up by some earlier test. Looking...

Disable mochitest layout/base/tests/test_bug607529.html on Android/opt for frequent intermittent failures; r=me,a=test-only
Disabled on android/opt for now, since it's failing so frequently. I'll try to get it running again next week, or find a better owner.

Coming back to check on this (sorry for the delay), I find:

The test passes test-verify:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=5164f1447d9a54e8abfd95ba4f839b85afb68e5e

It runs well on its own on try:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=7986d7ac2ca9eda26422c4882a448acd162a67af

And it doesn't cause other mochitest failures:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=fd712e1bde90edeb300a6405a973e44babcc0d0d


So I'm not sure what happened here, but it looks like it can be re-enabled now.
