"/datapack enable" shows success message after the command is run rather than after a data pack is enabled

When using /datapack enable to enable a data pack, the message below is shown right after the command is run instead of after the data pack is successfully enabled:

Enabled data pack <name>

This causes inconsistencies with /datapack disable which now shows the message below if successful to check for potential crashes before disabling a data pack:

Disabled data pack <name>
