For example:

If I make AppsGridViewTest : public testing::WithParamInterface<bool>, then instantiate parameterized test cases, the second test case will crash:

I can fix it by adding std::unique_ptr<aura::Env> env_ to AppListTestSuite just like: https://cs.chromium.org/chromium/src/ui/aura/test/run_all_unittests.cc?q=auratestsui&sq=package:chromium&l=31

However, I lack the knowledge to explain it. cc sky@, sadrul@ for guidance.
