Hi Richard, This is because the sequences include U+0EBA which was added in Unicode 12.0. Edge has not updated for Unicode 12 at this time.

I trust this is just a temporary aberration. Also with the sequence <U+0EBA, U+0EB4 LAO VOWEL SIGN I>, as in the nominative singular ສັນທິຕ຺ຖ຺ິໂກ of ສັນທິຕ຺ຖ຺ິກະ, which transliterates as sandiṭṭhika. This last example displays perfectly well on HarfBuzz renderers. Richard.
