Feature Request

esbuild.footer option was specified. But this option is deprecated and will be removed in future versions. This option can be achieved by using a plugin with transform hook, please use that instead.
– #1715

We need to create a custom plugin to add a footer. We currently use a footer to add code at the bottom of background, unlisted, and content scripts so they have a return value.

When we update to a plugin, we can fix some issues around the footer being applied too broadly. It should only be applied to unlisted and content scripts, not background or web workers.
