The bug
When using commands which have block coordinate arguments you are no longer able to tab complete them with the block coordinates of the block you are looking at or with tildes (~) if you are not looking at a block.
Affected commands are for example /clone, /fill and /setblock.

Lack of feature != bug, and it’s stated on the blog post that it’s only for literals as of now, it’ll be changed again to allow tab completing variables, eg coordinates as well. But until then: not a bug/by design.
Turn out I missed a single line from the blog post, tab completion missing has to be reported, my bad.
Autocomplete is currently only implemented for literals.
