A thread that starts from a poll (or any non-kind-1 post) is cached too, so a reload paints its replies at once.

The thread store accepted only kind 1 and silently skipped saving a thread
rooted in a kind 1068 poll — every refresh then waited on the relays behind
a spinner. Also guard the profile Back listener for window-less tests.
