Your assertion that "it does take effect eventually" appears to not be true in reality (at least in this little test graph) (attached).

Looking at the code, there's an inline function, set_delay, that calls set_history().  And the SWIG goop appears to be correct.

Quit finding bugs in years old, assumed working code!

It looks like this has never worked, and maybe was never even implemented.  I'm combing through the appropriate archaeological strata in the tree to see if the needed handling was removed at some point, but it looks unlikely.

Also, I wonder whether it has anything to do with the fact that it's a gr_sync_block, and not a gr_sync_decimator.  The FIR filters are all
  gr_sync_decimators, and perhaps the block executors treatment of them and their history setting is the main difference here.
