Re: [PATCH v5 0/1] MR5861: mshtml: Implement visibilitychange event.

[Gabriel Ivăncescu (＠insn)]

Simplified this a bit, got rid of having to store list of GeckoBrowsers, now just iterating through the window map we already have to possibly dispatch minimize events. I thought of some ways to try simplify or get rid the refcounting for the hook, but couldn't figure out something better, if you have any ideas let me know.
