All work on Verbosio has effectively stopped because of this bug. Verbosio relies extensively on documents without windows. (Extra window objects are bloat.) Mutation events are also fairly important, as it is how Verbosio’s various pieces detect changes in the master document.
This sucks. This sucks the neutronium out of a black hole. A Verbosio build based on SeaMonkey 1.0 just became impossible, and that was a major goal I had.
UPDATE: Patch posted! I hope the reviewers like it.
I really should get around to requesting cvs checkin privileges for the main tree, instead of just docs…
