Similar to enableTransientTaskbar changes in
ag/Ifa929dca18437ae101cf3290feda4209790604d2
This method differs from enableManualTaskbarStashing in that we call it during setup/teardown and so in these cases TaskbarActivityContext
being null may be valid. For instance, as part of the teardown,
taskbar may have already been destroyed so enabling blocking timeout
may be a moot point — adding logs can help verify that assumption.
