STR: 1. Open about:home or about:newtab 2. Click the onboarding fox icon to open the onboarding overlay 3. Make sure the tours appear 4. Resize the window so that the onboarding overlay and the fox icon disappear 5. Resize the window again so that the fox icon appears again 6. Click the onboarding fox icon to open the onboarding overlay Expected result: The tours appear again. Actual result: The tours do not appear. See the attached tours_disappear_after_resizing.gif for the real action. Root Cause: We are doing lazy load of the tours [1], which is good. However, at the step 2, the tours got loaded into the overlay once so `_tourItems` would be loaded with tours. Then at the step 6 we thought the tours should be loaded already because `_tourItems` was not empty. But in fact, we destroyed the overlay and created one new overlay without any tour loaded.

I can still reproduce this bug after pull the latest Nightly. Could you confirm that?

Sorry, false alarm.

I have verified that this bug is fixed with today's nightly.
