User style sheets apply to pages immediately instead of waiting for reload. This seems inconsistent with user scripts, which must wait for a reload. An extension which uses both features will see inconsistent behavior.
This could cause a problem if a stylesheet hides all images by default, and expects a script to run after, which shows some of them.
On the flip side we have had developers coment and expect the scripts to run when installed, like styles. In general they are surprised you need to reload to get scripts to work.
I'm just going to do a quick hack to fix Chromium, then try something more clever and general separately.

Will this change how the Style sheet menu in Safari’s Advanced preferences behaves?
This patch won't affect Safari at all (it is Chromium-specific).
The future work I do won't affect Safari either, but because the behavior will be configurable and I won't change the setting for Safari.
