Enchanting in 1.14.3 on levels greater than 30 on a level 30 enchanting level results in too many levels taken.

In the release 1.14.3 using a level 30 enchanting setup and having levels greater than 30 results in levels being drained to 27. I was level 42, enchanting on a bow, and dropped down to level 27, this was repeatable on levels 35-40+ I did not test on levels 30-35.
