Basically, I found that according to the Anki docs, Migaku should be using gui_hooks for its use of JS bridges in webviews. As it stands, other addons creating their own webviews will have issues when installed alongside Migaku.
I believe the Anki docs refer to this as "monkey patching" and is discouraged due to unpredictable side effects.
