Bug - When the sidebar updates, hooks are established more than once

[earlSt1]

Hi, just noticed this while working on Compendium Folders. When the sidebar updates, a callback is created on the renderCompendiumDirectory hook, which references the same function. What this means is that every time the sidebar updates, the number of hooks that compendium browser has established double until the sidebar becomes unresponsive.

I'm currently on v10b288, using D&D5e v2.0.3 and Compendium Browser v0.8.1 (latest i could download from the module install list).

For reference, I think the bit of problematic code is here:

compendium-browser/compendium-browser.js

Lines 753 to 756 in d4181d3

	hookCompendiumList() {
	Hooks.on('renderCompendiumDirectory', (app, html, data) => {
	this.hookCompendiumList();
	});

Edit - Thought i was experiencing deja-vu, then i realised I raised this issue in the parent repo 😄
