Fix flaky test in core

[cythrawll]

Describe the bug Test is flaky to be of any use. Needs fixed.

To Reproduce Steps to reproduce the behavior:

1. Go to 'core/tests/acceptance/table-test.js'
2. Find test 'visiting /table'

Expected behavior Test should pass consistently and reproducibly.

Additional context Problem seems like reorder helper doesn't do it's job quite right and might be a bit overzealous in dragging.
