`hx-swap-oob` on breaks on `hx-boost` swaps (star button vainishing repo tab changes), so that was why I made `starBtn-oob` fragment. But `hx-swap-oob="outerHTML:..."` doesn't strip the wrapper element, adding `div` wrappers to star button on every star/unstar interactions. To fix this, dynamically put `hx-swap-oob` attribute to star button itself by using `.HxSwapOob` param. Signed-off-by: Seongmin Lee <git@boltless.me>
