Fixed in commit fa2f5db. The issue was that domtrip's children() method returns Stream<Element> directly, but the migration script incorrectly added .stream() calls on the already-returned streams. Removed the redundant .stream() calls on lines 58 and 59.

@waynebeaton as discussed in the EAC meeting this is one of a bigger PR about 500 LOC, so lots of lines changed and will likely require my attention to be adjusted so how much should one attribute the AI and how much should the one adjusting the PR be attributed? Would there even be a limit, e.g. assume we hit the 1000 LOC would it require any special attention?
