https://tbpl.mozilla.org/php/getParsedLog.php?id=36564412&tree=Try&full=1 It's silently hard-crashing in `db.endTransaction()`. A transaction is open and writes have occurred. A `catch (Throwable t)` block can't catch the issue.

Tempted to chalk this up to 2.2 misbehavior and disable the test...

Sanity check: Kevin, Aaron, do either of you have a 2.2 device on-hand to test a current fx-team build? Specifically: * Visit a page and immediately add it to reading list (long-tap the reader mode icon, IIRC) * Bookmark pages and add history * Import Android bookmarks and history If those three things work on 2.2, I'm very inclined to disable this test on 2.2.
