after deleting into black hole register, need to press 'p' twice

[pazams]

after deleting into black hole register: "_d
then immediately pressing 'p' or 'P' results in nothing.
pressing a second time does paste.

strangely, if navigating with normal mode 'j','k','l','h' before pasting, then pasting works on first 'p' or 'P' press as expected.
