The tests asserts on devices which are recognized as LargeTablet due to

https://cs.chromium.org/chromium/src/chrome/android/javatests/src/org/chromium/chrome/browser/bookmarks/BookmarkTest.java?q=BookmarkTest.java:464+file:%5Esrc/+package:%5Echromium$&l=457

This +1 was added last year in change https://codereview.chromium.org/2800763002

However large tablet style has been modified to match mobile style here https://codereview.chromium.org/2837643002

but the test cases from BookmarkTest.java have not been modified accordingly.
