The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/58a9ac7a9f534ef3cda229da75cff9e6f6487a24

commit 58a9ac7a9f534ef3cda229da75cff9e6f6487a24
Author: qinmin <qinmin@chromium.org>

fix a layout test crash due to no browser window

The test opens a link to a pdf, which results in a download and closing the
tab immediately.
As a result, the crash could triggered by potential race between shut down the
content shell and opening the download.
