 """Rebase DumpAccessibilityTree Tests.
 
 This script is intended to be run when you make a change that could affect the
 expected results of tests in:
 
     content/test/data/accessibility
 
 It assumes that you've already uploaded a change and the try jobs have finished.
 It collects all of the results from try jobs on all platforms and updates the
 expectation files locally. From there you can run 'git diff' to make sure all
 of the changes look reasonable, then upload the change for code review.
