the cooldown pie survives a /reload, and Bagnon's bags keep their order

- the cooldown pie, the GCD sweep, minimap pings and the map arrow draw again after a logout, login or /reload; they went blank until a restart, which read as OmniCC killing the cooldowns (2113)
- an addon's own font on a button label keeps its face, size and outline instead of being undone every frame, MikScrollingBattleText's reported look (2112)
- an empty label reads as nothing rather than an empty string, so Cartographer's map label keeps its colour; a slider thumb with no authored size takes its art's own size, so Dewdrop's Look'n'Feel slider moves (2109, 2110)
- Bagnon's saved bag list comes back in the order it was written, so the keyring stops jumping to the front after a restart; hovering a Bagnon bag costs a third of what it did (2111, 2114)
