Nearby water does not turn to frosted ice, when walking along big dripleafs with frost walker boots

The Bug:

Nearby water does not turn to frosted ice, when walking along big dripleafs with frost walker boots.

Steps to Reproduce:

• Build the setup shown in the attachment below.

• Equip some frost walker boots.

• Walk over the big dripleafs.
  → ❌  Notice how the nearby water is not converted into frosted ice.

Information:

Closely relates to MC-109914, however, I wouldn't consider it a duplicate since dripleaf is 15/16 blocks tall.
